When Will I Get an MRI to Find Out What is Causing My Headaches

A doctor might order an MRI for you when you have headaches every day or nearly every day or if your doctor ordered a CT scan and the results are not definitive if your headaches are associated with a new set of symptoms, or if your doctor is concerned you may have a structural issue causing the headaches.

MRI scans can visualize regions of the brain that may be hard to discern from the benchmarked view of CT scanning, which include the cervical spine and posterior fossa region of the brain. An MRI cannot diagnose migraines or cluster headaches or tension type headaches; however, an MRI may be useful to doctors on excluding other medical disorders that may present with headaches, including:

Is It Safe

People that have an implanted medical device need to ensure it is MR Safe. An MR Safe device is one that is not magnetic, does not have any metal, does not conduct electricity, and does not pose any other hazards.

The scan will be safe for those who have had heart surgery and for those in possession of the following medical devices. But it is very important you check with your doctor prior to having an MRI to ensure you can safely have an MRI with the following medical devices:

Surgical clips or sutures

Artificial joints

Staples

Cardiac Valve replacements (except the Starr-Edwards metallic ball/cage)

Vena Cava filters

Brain shunt tubes for hydrocephalus

Migraine

Migraine is a very common disorder of primary headache, affecting more women than men and usually beginning between the ages of 20 and 30. Pain is worsened with routine activity. Many patients stop routine activity, as patients often feel that they need to be at rest. Autonomic features such as nausea and/or vomiting, photophobia and phonophobia usually occur with a migraine attack.

The Role of MRI in Diagnosing Headaches and Migraines

Diagnostic imaging like MRI is typically not required to diagnose migraine, but it can be helpful in certain situations – particularly when there are red flags present or atypical features of the headache.

Are you required to get a brain imaging scan for your headache pain

The doctor may feel pressured by the patient to get a scan or practice defensive medicine and order a scan anyway.

Role of MRI in Diagnosing Headaches and Migraine:

Excluding Differential Diagnoses:

An MRI can help identify structural problems within the brain or surrounding tissues that are responsible for Some features of a headache should raise suspicion for If a migraine is associated with some unusual symptoms, such as a prolonged aura, paralysis, or dizziness, MRI may help determine if there is an underlying neurological pathology.

When is an MRI indicated for Headaches

When the headaches are severe or occur suddenly – this could mean you have an underlying, serious condition such as stroke or hemorrhage.

When there are neurological deficits – consider headaches with vision changes, weakness, numbness, or difficulty speaking.

Conclusion

MRI is important for assessing headaches and migraines for the exclusion of secondary causes as well as important serious underlying pathologies like tumors, vascular abnormalities, and structural lesions in the brain. MRI is not necessary for diagnosing primary headache disorders like migraine based on clinical features alone, but MRI is imperative for ruling out potential causes in the presence of “red flags” and atypical features. Other MRI techniques can detect subtle brain changes associated with migraine; however these aren’t yet specific, diagnostic, nor reliable on their own. Overall, MRI has a very important supportive role of ruling out other causes and keeping patients safe, but it is not a dominant part of assessing migraine, headache and common headache disorders overall.

Frequently Asked Questions

Q. What is the role of MRI in migraine?

MRI scans alone cannot definitively diagnose migraine, but can exclude other possible causes of symptoms that either share overlap or resemble those of migraine, and may reveal structural changes related to migraine.

Q. How does MRI detect the cause of headaches?

MRI is rarely needed for primary headaches but is needed when headaches are sudden, severe, and new; arise and continue in a new pattern; new neurological symptoms develop; or continue after previously effective treatment.

Q. What is the MRI brain migraine protocol?

For migraine patients, a standard MRI brain scan is performed using a simple protocol designed to give an adequate overview of the brain’s structure.

Q. What is a functional MRI of migraine?

Functional magnetic resonance imaging (fMRI) is a type of neuroimaging method to study activity in the brain by measuring blood flow changes and has been used within the area of migraine research.

Q. What is a migraine vs. headache?

A migraine is a significant neurological disorder often associated with moderate to severe headache symptoms, nausea and vomiting, as well as photophobia and phonophobia. Headache is a very general term to refer to a pain localized in the head. A migraine is a specific form of headache with specific characteristics, and has the potential for other more severe symptoms.

MRI (Magnetic Resonance Imaging) is a common medical imaging method that can yield crucial information regarding the structure and function of the brain. MRI finds application in numerous aspects of brain imaging. Some of the significant applications of MRI in brain imaging include:.

Diagnosis of brain disease: MRI plays a tremendously important role in the diagnosis of brain disease including tumors, stroke, multiple sclerosis, Alzheimer’s disease, and other neurodegenerative diseases. It can provide excellent images of the brain allowing doctors to assess the site of the abnormality or extent of the disease in the brain.

Evaluation of brain function: MRI can also be used to evaluate how the brain is functioning by assessing various blood flow, oxygen consumption and other measures of metabolism to see if the brain is functioning to a normal level (or not). This is done with the technique of functional MRI (fMRI). This is often done by looking at brain activity while performing different actions or tasks, or in response to different stimuli.

Monitoring brain disease: MRI can be used to evaluate the changes that occur within the brain with brain diseases over time. This can help doctors make conclusions about what treatment to offer and when to change the treatment.

Planning for brain surgery: MRI is often used for planning brain surgery. MRI can produce high quality images to obtain high quality pictures of the brain and its structures. This is helpful for surgeons to determine how and where the surgery needs to be performed and to avoid injuring any critical brain structures.

An MRI (Magnetic Resonance Imaging) of the head is a form of diagnostic medical imaging that produces very clear pictures of the brain, skull, and surrounding tissues using radio waves and a large magnetic field. It can produce very high definition images of the brain which allow doctors to identify disorders like tumors, hemorrhage, strokes, inflammation, infections, and other abnormalities.

For an MRI of the head, the patient lies on a slide table that goes into the tunnel-shaped machine that uses the board and a magnetic field to identify images related to the head. The sterile equipment forms a strong magnetic field around the head region in order to use the body’s water molecules proton alignment. After creating the magnetic filed the MRI machine sends radio waves into the body, and the water protons will emit a signal that the MRI can sense and generate images. The MRI is a non-invasive procedure, which means the procedure does not require surgery and does not use ionizing radiation, making the MRI a very safe and effective diagnostic tool.

Why is a head MRI necessary?

Your physician may suggest you have a head MRI due to a variety of conditions. Some of the most common include:

Headaches: If your headaches are severe or frequent, it is possible a head MRI will be ordered to find the exact cause.

Seizures: An MRI of the brain may be used to locate the source of seizures.

Vertigo or dizziness: If you have repeated episodes of vertigo or dizziness, your doctor may request an MRI to help determine the cause.

Stroke: An MRI can be used to diagnose a stroke and determine its location and extent.

Tumours: If there is a suspicion of a brain tumour, an MRI can be ordered of the brain to look for tumours.

Trauma: An MRI can be used to assess brain injury after a traumatic injury such as a concussion.

Multiple Sclerosis: The disease, multiple sclerosis which is an attack on the central nervous system, can be diagnosed and followed using an MRI.

Types of Head MRI Scan

There are several types of head MRI scans, all of which serve different purposes. The most common types of scans include:

T1-weighted MRI: This type of MRI scans is great for producing good images of the white and grey matter of the brain.

T2-weighted MRI: This type of MRI scans is effective at visualizing changes to brain tissue associated with disease or injury such as swelling, infection or inflammation.

FLAIR MRI: These MRI images are valuable for evaluating fluids in the brain due to potential abnormality that is causing the pathology seen with brain tumours and multiple sclerosis.

Diffusion-weighted MRIs: Used for their sensitivities to identifying changes in brain tissue due to strokes and other disease processes, diffusion-MRIs identify changes in brain tissue due to limitation of the movement of the water molecules.

Perfusion MRI: This type of MRI scans measures perfusion or blood flow to the brain and can highlight areas of brain tissue where blood flow has been affected due to disease such as stroke or other disease characteristics.

Magnetic resonance angiography (MRA): This is an MRI scan of the brain with a focus on an evaluation of the blood vessels in the brain and will exhibit vascular pathology such as aneurysms and arteriovenous malformations.

How do I prepare for a head MRI?

Here are a few general tips to consider when making preparations for a head MRI:

Be sure to mention all of your medical conditions, including kidney disease, to your doctor for the needed preparation process an MRI may require.

Be aware of any specific preparation advice your doctor may give you. This could mean stopping specific medications for a specific time period before the study, or perhaps dressing comfortably in non-metal zippers or buttons.

Metal can interfere with the magnetic field and produce images that are not as clear, so prior to your scan, remove all metal jewelry and accessories.

If you have any implants or devices with metal in your body including pacemakers, cochlear implants, metal plates, or screws in your head, let the MRI technician know. Some of those items may not be safe with an MRI.

If you are claustrophobic or are anxious about being in confined spaces, talk to your doctor about if any medication or relaxation techniques might help you.

What is the process of a head MRI?

The typical head MRI procedure is:

Prior to the MRI test, you will change into a hospital gown and remove all jewelry, watch, and hairpins prior to your test. The technician may have you complete an MRI Head Screening form for your safety during the MRI.

You will be lying down on a sliding table that will enter the MRI machine. Your head will be placed in a head rest, and the technician may put a coil around your head to improve the clarity of the image.

To help reduce the noise of the machine, the technician can provide you ear plugs or headphones for the test. The technician will communicate with you during the scan via a two-way intercom, and during the scan to reduce image blurring, you will be asked to hold as still as possible.

The MRI scanner will take pictures of your brain while it makes a variety of annoying thumping and buzzing sounds. Depending on the scan and the amount of information needed, the scan could take 30 – 60 minutes to complete.

Once the scan has completed, the technician will help you off the table and provide you some last instructions. After the scan, you may continue with your regular activities right away.

Conclusion

An MRI scan of the head is a safe, non-invasive test that can produce detailed images of the brain and head tissues. It is important to prepare properly for the MRI scan. Removing all metal items and being truthful with your doctor about pre-existing health conditions are all ways to ensure the MRI scan runs smoothly and the results are accurate.

Remaining still and paying attention to the appropriate responses during the MRI scan are essential for obtaining clear images of the head.

After the MRI the patient usually can return to their usual activities, and the doctor will discuss the results with the patient and also discuss next steps. If at any time during the MRI process you have a question or concern, do not hesitate to ask your healthcare provider.

Frequently Asked Questions

Q. What do I need to do to prepare for a head MRI?

You need to remove all metal objects (jewelry, hairpins, eyeglasses, etc.), wear clothing made of non-metal material, and notify the staff about any implants, pacemakers, or conditions such as claustrophobia or kidney problems.

Q. Should I eat, or take my medication, before my scan?

You will usually be able to eat and take your medications as prescribed unless your doctor has specified otherwise (e.g. if you will receive contrast dye).

Q. What will happen during the head MRI?

You will be lying on a table which slides into the MRI machine. Because of the loud noise a head MRI causes, you will be given earplugs or headphones to wear.

Usually, there are no special instructions after a head MRI. If you received contrast dye, you should watch for rare allergic reactions, and continue medications as directed.

An MRI of the head is a diagnostic test that causes no pain to the patient, and utilizes a very large magnet and computer to create digital images of the brain and the tissue surrounding the brain. This is a noninvasive test and does not use radiation.

An MRI of the head may be used to diagnose:

Brain tumors

Stroke

Head trauma

Multiple sclerosis

Alzheimer’s disease

Hydrocephalus

Aneurysms

Infection

An MRI of the head is also used to monitor the brain before surgery, after surgery and during treatment of conditions related to the brain.

How a Head MRI Works

A head MRI works by applying a magnetic field to align the atoms in the body. The atoms are disturbed and send out a signal that is recorded by the MRI machine when radio waves are passed through the body. The MRI machine uses the signals to create images of the body.

Head MRIs are usually performed in a hospital or clinic setting. The patient will lie on the table of the MRI machine that fits into the MRI machine. A coil will be placed around the patient’s head to transmit and receive the radio waves. The patient needs to remain still during the scan which will last 30-45 minutes.

Conditions that Can be Diagnosed using a Head MRI

There are several conditions that can be diagnosed with a head MRI. Some of these issues include:

Brain tumors: Brain tumors form when cells begin to grow in a way that disrupts the surrounding cells in the brain. Tumors can be either benign or malignant. A head MRI can identify the tumors, their size, shape, and whether they are near surrounding structures.

Strokes: If there is a disruption in blood flow through the arteries in the brain, it causes there to be a shortage of blood flowing to the tissues. An irregularity in blood supply will disrupt the tissues it supplies, causing cell death. A head MRI can diagnose strokes and if there is brain damage from the stroke.

Head injuries: with head injury can create multiple problems for the patient including bleeding, swelling and damage to the brain. A head MRI can provide the treating physician how bad the head injury is and whether a brain injury has occurred.

Multiple sclerosis: Multiple sclerosis (MS) is primarily an autoimmune disease of the CNS, and causes inflammation and damage to the myelin sheath.(covering layer over nerve fibers). A head MRI can provide evidence that will help settle a diagnosis of MS and determine extent of disease.

Alzheimer’s Disease: Alzheimer’s disease is characterized as a brain disease that causes dementia. It consists of cell death and an accumulation of amyloid plaques and tau tangles in the brain. Minocycline Can Head MRI to Diagnose Alzheimer’s disease, and hopefully assess how advanced it is, i.e. prognosis.

Hydrocephalus: Hydrocephalus is defined as the accumulation of cerebrospinal fluid (CSF) in the brain where the brain and spinal cord are both surrounded by the same fluid and enveloped by a big protective CSF sac for shock absorption. This accumulation of fluid, enlarging the brain, is the definition of hydrocephalus. A head MRI could be ordered to ascertain hydrocephalus and stage the extent of hydrocephalus.

Aneurysms: A “bag” from the walls of blood vessels (protrusion). Aneurysms happen in the brain or any other place in the body. Aneurysms may burst, bleed and can be fatal. A head MRI could be used to help determine if there are aneurysms and assess potential for aneurysmal rupture.

Infections: Brain infections can be anything from something tiny like a bacteria or virus. Infections can also present with many different symptoms such as fever, headache, nausea/vomiting, and seizures. A head MRI could be used to determine if they are brain infections and assess the degree of infection.

Benefits of a Head MRI

Head MRI scans are very valuable in diagnosing a number of different ailments. They are noninvasive, and they do not use radiation, however they provide clear images of the brain and structures in the head. Even the cost of a head MRI scan is very reasonable.

Some of the advantages of a head MRI scan are:

Correct Diagnosis: A head MRI scan can detect a variety of conditions including tumors, strokes, aneurysms, infections, and other abnormalities within the brain and surrounding tissues.

Non-invasive: MRI does not involve radiation unlike a CT scan or x-rays, making MRI a safe option for certain patients.

High Definition Images: MRI creates high-definition images of the brain, allowing physicians to evaluate the anatomical structure of the brain in detail, and discover abnormalities.

Multifunctional: MRI can evaluate a variety of conditions such as traumatic brain injury, multiple sclerosis, and dementia.

Helpful in planning treatment: MRI scans might help physicians determine the best form of treatment for patients, such as surgery or radiation therapy.

Find conditions earlier: Conditions can be identified in the early stages so treatment can commence sooner, leading to better outcomes for patients.

Overall, MRI scans of the head serve as an excellent imaging and diagnosis method to assess and treat a multitude of conditions related to the brain and surrounding tissues.

Risks of a Head MRI

The risks and dangers that can occur with an MRI of the head are very small and there are very few patients who might complain of soft symptoms such as nausea or vomiting after the MRI. The chance of an allergic reaction to the dye or contrast material used in some cases during a head MRI is very small. Here are some of the potential risks of a head MRI:

Claustrophobia: Those with claustrophobia may find it difficult to undergo an MRI because they will have to lie still within a small tube for some time. Open MRI machines, or even sedation, can be utilized to help.

Metal implants: Those with metal implants such as pacemakers, cochlear implants, and certain types of metal dental implants may be moved or heated by the intense magnetic fields of an MRI machine. Individuals with such implants should consult with their doctor for the risks and benefits of an MRI.

Dye/allergic reactions: MRI studies require the use of contrast dye, which makes for a better picture, but can cause a very small number of individuals to have an allergic reaction. Individuals with allergies and/or kidney problems may be at even higher risk for reactions to the iron based ink.

Noise: MRI equipment produces clapping or thumping noises throughout the exam, and this sound can be unnerving or uncomfortable for some patients. Usually earplugs or headphones are used to fix this.

It is important to say that the benefits of a head scan by MRI will outweigh the risk for most people. The risks can be minimized by informing the radiologist about any medical

Conclusion

Head MRIs are essential diagnostic tests for many conditions and diseases. MRIs are not invasive, do not involve radiation, and produce very detailed images of the brain and structures in the head. If you have any health concerns, please consult your doctor.

An MRI, which stands for magnetic resonance imaging, is a diagnostic imaging test that utilizes magnetic fields and radio waves to produce sharp and precise pictures of your body. Most often, MRI scans use the head and neck to evaluate a variety of clinical conditions that may include tumors, infections, or injuries. 

If you have been given an appointment for a head and neck MRI scan then you may be feeling anxious. You’ll feel better once you know exactly what happens during an MRI scan. In this blog we will explain the process for head and neck MRI scans. 

Preparation for the Scan 

There may be specific directions you should follow prior to your MRI. This will almost always involve fasting from food or drink – you will receive direction from your doctor about this. Fasting is important, as food and drink can affect the quality of the image and can also make you uncomfortable if you have a full stomach during the scan. 

You will also need to remove all metal items from your person, including jewelry, wristwatches, and hairpins. Metal can interfere with the magnetic field and create poor quality images; therefore, being prepared for the scan is important! Additionally, if you have a pacemaker or other implanted medical devices, it is important that you inform your health provider in advance. 

If you feel anxious or claustrophobic, you can request a mild sedative to help calm you during your scan; however, you will need to have someone take you home since sedation may impair your judgment for driving. 

The MRI scan procedure 

On the day of the scan, when you arrive for the MRI, you’ll be asked to take off your clothes and put on a hospital gown. You’ll lay down on a thin table which then moves into the machine. The machine is a large, tube-like object with a stronger magnetic field than that of the Earth’s, hundreds of times stronger. 

During the scan, you will need to be still as motion will blur the images. The machine will make loud thumping sounds and tapping noises, and you will be given earplugs or headphones. You can listen to music or an audiobook, and so you have time to pass if you wanted to.  

There may be a time when you will receive an injection of a contrast agent, which is a special type of dye that improves the quality of the images. The contrast agent is generally injected in a vein located in your arm. You may feel a momentary sensation of heat, and/or a metallic taste in your mouth for a few moments and that should subside quickly. 

The scan can take anywhere from 30 minutes to 60 minutes, depending on what types of images need to be taken. If you have several scans done, you may need to move around quite a bit in-between scans. 

What happens after the neck and head MRI scan? 

After completing the scan, you may return to your own clothes and go back to your normal routine. There are no activity restrictions or dietary limitations following the scan, and you will most likely be able to drive home or go back to work straight away. 

The scan images will be forwarded to a radiologist, a medical specialist who interprets images. The radiologist will examine the images and forward a report to your doctor. Your doctor will sit down with you and explain the results and decide on the best action to take. 

Risks and benefits of neck and head MRI scan 

MRI scans are considered safe and non-invasive procedures, and best diagnostic centers in Rohini, Delhi offer discounts on the cost of head and neck MRI’s. Unlike X-rays, Ultrasounds and CT scans, MRI scans do not use ionizing radiation which can be harmful at large doses. There are still certain risks associated with the scan.  

One risk is the possibility of an allergic reaction to the contrast dye. While rare, individuals can have an allergic reaction to the contrast dye that can range from mild itching and development of hives to serious anaphylaxis.  

Another risk is claustrophobia, MRI units are a closed small space and some individuals may feel uncomfortable and anxious during the test. If you are claustrophobic, you can discuss taking a mild sedative with your physician or consider an open MRI.  

Despite the possible risk, there are many benefits to having a head and neck MRI scan. The MRI can find a variety of problems including tumors, infections, and injury, which will not show up on other imaging methods such as X-rays or CT scans. 

Conclusion 

A head and neck MRI is a non-invasive imaging exam, or test, using high-powered magnets and radio waves to create images of your body. This test is safe, and most people tolerate it well, but some may become anxious or uncomfortable during the exam. 

If you are having a head and neck MRI scan, it is important to follow your clinician’s instructions for preparation, and to inform them of any medical conditions and/or implanted devices. Knowing what to expect from the exam can help you feel less anxious or worried. 

If you have questions or concerns about the scan, you can speak to your provider about them. You can also call  carebox at any time if you would like to ask about the head MRI cost. Our partnered diagnostic centres offer head and neck MRI at lowest cost. They can provide you with additional information about the process, including any risks and benefits, and help you decide whether the scan is right for you. 

Introduction 

Head imaging is a valuable aspect of medical diagnostics, providing diagnostic information that is useful in evaluating the complex structures and conditions of the human head. Of the different imaging modalities, Magnetic Resonance Imaging (MRI) provides the most optimal means for acquiring a hard-copy image of the head with the greatest precision. 

MRI leverages the components of strong magnets along with radio waves to create high-resolution images of the head that enhance the ability of a healthcare professional to investigate the brain, skull, blood vessels, and other structures of the head. MRI is a non-invasive imaging method that allows for significant flexibility within the imaging study and has transformed the field of diagnostic medicine by establishing the ability to detect and characterize many neurological disease processes, acute injuries, tumours, vascular diseases and developmental disorders. 

With the imaging capabilities of MRI and its ability to create images that are accurate, detailed, high in quality, MRI will continue to lead in head imaging, allowing health care providers to accurately establish diagnoses and subsequently develop relevant treatment protocols to improve patient outcomes. 

Understanding the principles of Head MRI 

Head MRI, based on the basic principles of MRI technology, depends upon the interaction of magnetic fields and radio waves to create images of the head. The MRI scanner generates a strong magnetic field, a strong, homogeneous magnetic field all around the head of the patient when inside the scanner. When applying radio waves to the head, those hydrogen atoms in the body align with the magnetic field. Once the radio waves are turned off, the hydrogen atoms release energy back to the detector coils.  

That metered energy is received and processed by the computer to create accurate cross-section images of the head. Within the MRI scanner, there are many components, including the gradient coils, and radiofrequency coils, all of which work together to manipulate the magnetic field in order to create accurate images of the structures of the head. 

These images are rich with diagnostic information for the physicians involved with the diagnosis and assessment of conditions such as brain tumors, stroke, and neurological diseases. 

The foundation for head MRI rests on this sophisticated imaging technique employing a wonderful non-invasive technique to observe the precise anatomy and pathology of the head. 

Various modalities of head MRI 

Head MRI scans are just one imaging technique, but there are many head MRI scans continually providing new information with respect to brain structure, brain function, and brain perfusion. The key types of head MRIs include the following: 

Structural MRI: Structural MRI is the most common form of brain imaging. Structural MRI provides detailed, anatomical data regarding brain structure and abnormalities. The two methodological approaches that we use are: 

T1-weighted imaging: T1-weighted imaging describes contrast among various brain tissues, which provides excellent visualization of brain structure. T1-weighted imaging is very effective at showing lesions, tumors, and cortical atrophy. 

T2-weighted imaging: T2-weighted imaging describes contrast based on differences in the water content of tissue, and provides good detection of abnormalities based on increased water content, including edema, inflammation, and white matter lesions. T2-weighted imaging is extremely relevant for identifying diseases such as multiple sclerosis. 

Functional MRI (fMRI): At present, functional magnetic resonance imaging identifies the hemodynamic responses and alterations in oxygenation associated with activity in the brain. It can help localize activity in the brain, and clearly demonstrates the regions of the brain that are active in the different cognitive domains, such as language, motor activity, and memory. fMRI is important in research and particularly in presurgical mapping to identify functional areas that are preserved when surgery of the brain occurs. 

Diffusion Tensor Imaging (DTI): Diffusion Tensor Imaging (DTI) is a more complex form of MRI that measures the movement of water molecules in brain tissue. Diffusion tensor imaging is unique as it illustrates white matter tracts in the brain and informs on the connectivity and integrity of the brain.  DTI data is particularly useful in the assessment of stroke, concussion, traumatic brain injury, and neurodegenerative disease. 

Perfusion MRI: Perfusion MRI measures blood flow in the brain, providing information about tissue viability, vascular malformations, and ischemic change. Perfusion MRI is useful in diagnosing brain tumors, grading brain tumors, and observing treatment response. 

Magnetic Resonance Angiography (MRA):  MRA obtains images of the vascular structures of the brain and neck. By using a specialized contrast agent or time-of-flight technique, MRA can identify (in a broad range of cases) aneurysms, vascular malformations and vascular diseases. Thus; MRA has a significant role in neurosurgical planning and diagnosing cerebrovascular disease.  

Susceptibility-Weighted Imaging (SWI):  SWI is exquisitely sensitive to hemorrhages and products of blood degradation. It provides exquisite detail regarding microbleeds, small veins and iron deposits; therefore could potentially help identify and characterize brain lesions from trauma and stroke as well as neurodegenerative diseases like Alzheimer’s disease. 

Applications of head MRI 

Head MRI is an important modality for the diagnosis and subsequent management of many conditions. Some of these include: 

Brain Tumors: MRI provides detection and characterization of brain tumors, which is important for planning treatment. 

Stroke: Used for the diagnosis of acute strokes, assessing their severity, and attempting to determine the cause. 

Traumatic Brain Injury: MRI is used to assess brain injuries, and evaluate for bleeding, contusions, and axonal injury.  

Neurodegenerative Diseases: Used to assist in the diagnosis of and follow management of diseases including Alzheimer’s disease, Parkinson’s disease, and multiple sclerosis. 

Vascular Issues: MRI is able to identify aneurysms, arteriovenous malformations (AVMs), and other vascular pathologies of the brain. 

Epilepsy: Head MRI helps identify structural abnormalities of the brain that may be the cause of seizures and inform therapy. 

Infection and inflammatory diseases: MRI can be used to diagnose brain abscesses, meningitis, encephalitis, and other inflammatory processes, and guide diagnosis and management. 

Hydrocephalus: MRI contributes to work-up of cerebrospinal fluid accumulation in the head, the underlying cause, and how best to manage it.  

Pituitary Disorders: MRI helps to look at pituitary tumors and note their size, location, and effects on nearby structures.  

Cranial Nerve Disorders: MRI helps to identify cranial nerve lesions/compressions, which is important in diagnosing trigeminal neuralgia or Bell’s palsy.  

Head and Neck cancers: MRI is extremely useful in staging and follow-up of head and neck cancers, to assess the size, extent and involvement of neighbouring structures. 

Price of Head MRI 

To determine the cost of a head MRI we will need to be familiar with what goes into the cost of this diagnostic imaging service. There are many variations to the cost of a head MRI, including where the MRI is performed, what kind of hospital and/or facility is providing the service, if the MRI lacked complexity, where it is not uncommon to receive and additional services. In addition, insurance should be taken into consideration, and there will be differing individual health plans in relation to out-of-pocket costs for a head MRI. 

Although it is exceptionally challenging to give you a precise price tag on a head MRI, it is still possible to consider the quality and cost of this diagnostic service. 

Typically the head MRI scan ranges between 4500 to 5000 INR, this price is subject to change. Contact Carebox  to understand about the cost of a head MRI scan near you.  

Conclusion: 

Last but not least, a head MRI is an important diagnostic tool that can provide rich information on brain structure and function. Whether for evaluation of neurological disorders, detection of tumours, or assessing the sequelae of a concussion, head MRI’s are an important adjunct decision-making tool and diagnostic tool. 

Though the cost of a head MRI can often be variable depending on numerous reasons, it is important to consider the balance of quality and price. An intentional plan should be made to pursue way to get the best imaging modality possible while searching for multiple alternatives, obtaining insurance coverage, and applying for financial assistance, so as to not jeopardize one’s economic state. 

Ultimately, the benefits of a head MRI with respect to early diagnosis, improved treatment planning, and overall patient care, far outweigh the potential cost concerns, and is integral to modern medicine.

Q. What do I need to do to be ready for a head MRI? 

You may be asked to not eat or ingest anything for a period of time before the scan. You will be asked to take off all metal items (jewelry, watches, hairpins) and to wear comfortable clothing that does not contain any metal, such as buttons or zippers. Be sure to inform your physician if you have any metal implants, metal fragments, or if you have a history of kidney disease. 

Q. What happens when I have my scan done, and how long does it take? 

You will be placed on a table that moves you into a tube-like scanner. The procedure is not painful to you, but it may be loud. If you are still concerned about the noise, earplugs are often available. Typically head MRI’s take between 20 to 60 minutes, depending on how many images are needed and, if a contrast dye is going to be used. 

Infections of the spine are not common, but can occur and can lead to serious illnesses when caused by bacteria, fungi, or viruses that invade the spine. The invading organisms can infiltrate nearly any structure in the spine that one can imagine, including the spinal cord, the spinal canal, the meninges, the vertebra, and the spinal discs.. 

When these critters invade spinal discs, we call that inflammation discitis.  When these critters invade the actual bones of our spine, we call that osteomyelitis. 

As a rule of thumb, these infections travel to the spine from the circulatory system, blood. Normal bacteria, that is Staph or E.Coli, enter the bloodstream from an incident such as surgery or IV drug use – and bingo! 

Simply put, spinal infections can be catastrophic to your spine! A cold has an element of danger, but you can mess up your spine with spinal infections.As your spinal discs become inflamed due to disease, inflammation, ultimately can lead to disc degeneration, and even disc necrosis. If the infection travels to the vertebral bodies it can create fractures in the spinal column itself. Spinal fractures will create extreme instability in the spine. This means the weight of your torso may cause your whole spine to lean forward  Kyphosis is a spinal deformity in which the thoracic spine, or upper back, develops a forward hump. 

Other problems associated with spinal infections are pain from nerves and the accumulation of pus, referred to as an abscess. Abscesses—not only are they excruciating pain but they can also compress the spinal cord. When narrowing of the spinal canal occurs – spinal stenosis – this could cause paralysis, weakness of the muscle and nerve pain.  

Symptoms of Spinal Infection 

So it is very important that you follow any protocols your doctor directs you to regarding MRI preparations. But if you’re not directed to any protocols, you should try to maintain your level of routines that you follow for the days and weeks leading up to the scan as best as possible. This includes normal activities and taking medications as prescribed. By sticking to your pre-MRI protocols, you can feel confident that you received the most accurate scan possible with no impacts of a routine change affecting your results. 

How are Spinal Infections Diagnosed? 

Diagnosing spinal infections will likely involve both imaging studies as well as laboratory investigation. Once an infection is suspected, the doctor will most probably imaging with X-ray before anything else. While the X-ray does not delineate soft tissues (and therefore is not able to depict the spinal discs), the imaging study can show bone erosion or loss of disc height  (loss in disc height is shown by loss of space between two vertebrae) . As easily as an MRI gives information on soft tissue along with bone status, your doctor may proceed with that if the X-ray picks up concerns on the disc or on the bone. 

identifying a spinal infection through laboratory tests based on an inflammatory marker or white blood cell count.The other markers are C-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR). In 85% of all spinal infections, the abnormal markers will be the ESR and CRP.  Additionally, your doctor may also do a blood culture for an attempt to grow the virus that is initially causing your pain. In less than 50% of episodes of spinal infections, blood cultures grow the pathogen. 

Conclusion 

Spinal infections are a rare but serious problem that warrants immediate medical attention due to the potential for significant pain, nerve injury, spinal instability, and complete motor paralysis. Early diagnosis via imaging studies and laboratory investigations is critical to minimize the potential for complications. Time is critical in the successful medical treatment of a spinal infection, and early intervention can save the important structure and function of the spine from irreversible damages. 

Frequently Asked Questions 

Q. Can you recover from a spine infection? 

Yes, with treatment you may recover from a spine infection. 

Q. How long can a spinal infection go untreated? 

Within 48-72 hours. 

Q. Is spinal pain Curable? 

Most back pain gets better within a month using the right treatment.  

Not many people will say they enjoy getting an MRI. If you are like most people, you may have this reaction when your physician suggests an MRI or you receive a letter to have one: your hands start shaking, your palms start sweating, and your heart and mind race with fear as you contemplate the possibilities. 

If your physician has suggested having an MRI scan you may well be in shock just like this. First of all, you should know that you are human, and the above reaction is one we all have, and you are most certainly not alone! The MRI scan itself is not as impressive as you might expect, even if the thought of it can be scary! You will simply lie still for a little while during this easy process. 

It’s one thing to say to yourself not to worry; it is another to do it. to give you the confidence you need to walk into your MRI with the least amount of tension or worry. We want you to know what you can expect so that you can be prepared. We are going to walk you through the MRI preparation, we are going to help you understand the MRI process and, what you can do and not do before, during and after the MRI. You will be feeling a lot more comfortable when you face the MRI fully armed with knowledge. 

How to prepare before an MRI? 

Did your doctor order or recommend an MRI for you soon?  If so, breathe….you’ll be fine.  Don’t get too anxious.  If your concern is anxiousness about the MRI, try redirecting that anxiousness toward the prep work for your scan.  You should do this before an MRI. 

Inform Your Doctor If You Have Claustrophobia 

You will be lying down in a cylindrical, closed machine during the MRI. The amount of time you will spend in the machine depends on the study, maybe up to an hour. For patients who have had experience with claustrophobia, this can create a high level of anxiety. To make the process more bearable, talk with your physician before the study and explain your fears as well as your history of claustrophobia. Your physician may write an order for an anti-anxiety medication that you may take before the study, to help you stay calm during the MRI. 

Leave Your Jewelry at Home 

Wearing metal is obviously high among the things to avoid before having an MRI. Because an MRI is practically a huge magnet, the MRI technicians will ask you to take off everything metal from your body before you enter the machine, even rings and jewelry you are wearing. If you all you wear are cheap pieces, it may not be a big deal. If it is on the other hand taking off expensive pieces of jewelry that have cost a lot of money and can’t easily be replaced, perhaps it might be better to leave it all behind altogether! Although it probably is very unlikely anything could happen during your scan, it’s probably just safer to reduce the risk of losing them. 

Be Honest With Your Doctor 

Some situations may change the MRI exam; for example, any metal implants in your body could be a problem as this scan is essentially a big magnet. Specific items to be cautious of include: 

– A history of kidney disease 

– A history of diabetes 

– Pregnancy 

– A pacemaker 

– An implanted drug delivery system, such as an insulin pump 

– Previous shrapnel or bullet wounds 

– Cochlear implants 

When your doctor assesses the safety of an MRI, they will consider an extensive list of conditions like those mentioned previously.  Be upfront and honest with your doctor. Any deception regarding any part of your health history can impact your scan results!  Reviewing your health history might be the most important aspect of preparation for an MRI. 

What to Avoid Before an MRI? 

Having learned a bit about how to prepare for an MRI in the future, let’s turn our attention to the other side of things—what not to do leading up to an MRI? Here are a few of the top considerations.  

Do Not Get Any New Piercings  

When you report for your MRI, you will need to remove all body piercings and body jewelry. If you have healed piercings, this generally will not pose a problem. If you have a newly healed and theoretical piercing, it may start to close up rapidly during the course of the MRI observation. In order to avoid the loss of existing piercings, please do not get any new piercings in the weeks leading up to your MRI. 

Follow Doctor’s Orders 

You should trial and follow your doctor’s orders if they advise you to try another diet and avoid certain foods before your MRI. Likewise, if your doctor advises you to change your routine, try a new medication, discontinue an old medication, or increase your level of activity, you should do what they say.  This will only make your MRI go more smoothly and be accurate when it gives your doctors and care team the best chance for giving you the best care they can. 

Do Not Change Your Normal Routine 

Whatever changes your doctor suggests, make sure to stick to those!! If you are not given any recommendations and your scan is in days or even weeks, try to stick to routine as best as you can. This means to keep doing your normal activities, and taking any prescribed medications as directed. Sticking to your pre-MRI routine means that you can be confident that you are getting the most consistent scan possible, and that any changes in your normal routine did not lead to incorrect results. 

Conclusion 

Undergoing a head MRI may seem overwhelming, but having a basic understanding of the process and how to prepare for your visit, will save you valuable time in the process and help put your mind at ease. Many people feel anxious or nervous. That is a completely normal feeling! Following the recommendations to inform your doctor about your situation, properly preparing for the scan, and not making changes to your routines before the scan, are all the ways you can make the scan more productive and enjoyable for you. One final point: you won’t be able to wear your jewelry during the scan, and please be honest with your doctor about your medical history. Moreover, if you are concerned about claustrophobia, ask your doctor about any other options that may be available. 

A head MRI is safe, painless, and an important diagnostic tool that helps your medical staff care for your needs. With the proper planning and accurate perspective, the experience will likely not be as frightening as you had previously perceived it to be. Please take a deep breath and know that you are taking the next logical step towards better health and well-being. 

Frequently Asked Questions  

Q. What should I wear or bring to a head MRI? 

Wear loose-fitting, comfortable clothing without any metal. You will most likely be asked to put on a hospital gown and you will need to remove all metal, including jewelry, watches, eyeglasses and hairpins. 

Q. Can I eat or take my medications before the scan? 

You can usually eat and take your regular medicines, but check with your doctor if you are not sure. If a contrast agent is used, you may be asked to fast for a few hours in advance of the appointment. 

Q. Are there any medical conditions I should tell my doctor about? 

Always be sure to tell your doctor, and the MRI staff, if you have any metal implants, pacemakers, artificial joints, kidney problems, allergies to contrast dye or if you are pregnant or breastfeeding. 

Q. What can I expect during the MRI scan? 

The scan will not hurt, and on average it will take 30–60 minutes. You will be lying very still in a tube-like machine. The machine can be a little loud, but you will usually be given ear plugs or headphones. 

Q. What if I’m claustrophobic or worry about the scan?  

If you suffer from claustrophobia or anxiety, please tell your doctor prior to the scan. They will consider prescribing you some medicine, or possibly an “open” MRI to make your appointment more comfortable. 

How Long Does It Take to Prepare MRI Scan Reports? 

Getting MRI results can take different amounts of time. When you have your doctor order the MRI, you can ask how long it will be to get your results. You can also ask the person who interprets the MRI results how soon you can have a copy of the MRI report. 

An MRI (Magnetic Resonance Imaging) scan can produce many very detailed pictures of your body using a magnetic field. Your doctor may order an MRI when they need to see important structures in your body like your joints, blood vessels, heart, and more. 

How long the results take to get back depends on all sorts of variables. An example can be whether you got the MRI for an emergency reason. Read below to see when you might expect to find out your MRI results. 

How quickly will you get results? 

Different factors can affect how long it takes to get your MRI results. They include: 

If you had an emergency: If you had the MRI for an emergency, you will most likely get MRI results faster than if it was scanned for a non-emergency. 

Who is reading your MRI: A physician reads the MRI. Sometimes, the results of the MRI will be read by a doctor specialist, called a radiologist. The radiologist may send their report of the MRI to the doctor that ordered the MRI. Your doctor may read the MRI and draw their own conclusions and recommendations to you. 

Why are you getting an MRI: If you are getting the MRI for a cancer diagnosis, staging, or assessment of care, there may be several medical specialists that need to review and comment on the MRI findings. When this is the case, getting information about your MRI will take longer. 

Generally, you would expect to wait about 1-2 weeks to receive information about your MRI scan results. 

What might delay the MRI scan report? 

After receiving an MRI, the radiology technician will typically send the images, or provide a notification securely to the radiologist that the images are now ready to be reviewed. Some offices do have radiologists on staff to review images, but others will utilize radiologists who may not live nearby, who will read and interpret the MRI images. 

Then, the radiologist will prepare a report of their findings. If emergent findings are present, they will communicate with the doctor or facility responsible for taking care of the patient. If it does not appear there are any emergency findings, they will send the report to the requesting doctor. 

Your MRI will be sent along to the physician that requested it and they will take a look at the images as well. Your doctor will determine if they will agree or disagree with the conclusions of the radiologist; and they may also seek a second opinion from another specialty physician. 

Your doctor will explain the results of the MRI and indicate what they mean either in a phone conversation or at a follow-up visit. 

In most situations, the doctor, radiologist, and other medical providers are all tied up working in busy seasons. Reading and interpreting MRI findings typically does not consume the use-provider’s time, but it doesn’t take much time. 

How does it work? 

Magnetic Resonance Imaging generates magnetic fields that bounce off the body to form images. The imaging process itself does not hurt, but it will be between 15 to 90 minutes depending on what the MRI is looking at. 

When it is time to do the MRI, you will lie down on a flat surface shaped like a cylinder. The bed will move into and out of the tube so the MRI machine can get the images it needs. The MRI machine is incredibly noisy because of the extreme effort it takes to produce a magnetic field. You will typically get ear plugs or headphones with music to provide some relief from the noise.  

Often, you will get intravenous (IV) contrast dye, which can allow your doctor to see areas that are more metabolically active in your body. The IV dye travels to many areas of the body, and this may allow your doctor to see abnormal areas (like cancerous tumors) more clearly.  

Most of the time, MRIs are not done on an emergency basis, and the MRI will be done at an imaging center. Most MRIs can also be done at the hospital where you are being treated. 

Where do you get your MRI scan? 

The physical location where imaging is acquired can affect turnaround time for receiving your imaging results. In areas with less availability of healthcare resources and/or a higher patient to available resources ratio (i.e., less healthcare available) there may be longer delays attaining MRI scheduling. Waiting for the MRI itself may take longer depending if there is waiting time to schedule the procedure and then await the results. In locations with higher density of medical centers and expert imaging radiologists, the review and interpretation of the MRI scans may be more efficiently done and thus have faster turnaround times to get the results. Additionally, how effective the healthcare system/healthcare infrastructure operates, together with the use modern next generation imaging modalities, systems, and electronic interpersonal communications can also affect the time it takes to reach your imaging results. 

How Can I Shorten the Wait For My MRI Results? 

Online subspecialty second opinions will provide a route to receiving timely MRI results. If you have a wait time of weeks or days, this type of service can allow you to have your results sooner. You may get a copy of your images from the hospital or imaging center, where an employee will make you a CD containing a copy of all your images. In most cases, this may be done for you at the time you leave. You can then transfer the research images from the CD directly to the second opinion interpreter.  

To ensure that you are receiving the proper interpretation for your study, ensure that you are using a service that connects you to a radiologist/subspecialty radiologist, and not a generalist. Subspecialists have been trained and experienced in the interpretation of MRI scans for the specific body part or body system that your MRI is interpreting.  

After you submit your scan, your MRI results will be provided to you within 24-48 hours and you may share that report with your treatment team, such as your primary care physician or the referring doctor who made the MRI request. 

Frequently Asked Questions 

Q. How long does it take to prepare an MRI report? 

The preparation of an MRI report usually takes 4 or 5 hours after the scanning is complete, as the radiologist will need time to carefully examine the images and document the results. 

Q. When will I get my MRI results? 

Most patients get their MRI results within 1 to 2 weeks, although this will depend on the facility, complexity of the scan, and radiologist’s workload. 

Q.  Can MRI results be expedited in urgent situations? 

Yes, in urgent situations (like a possible stroke or emergencies), preliminary MRI results could be available within a few hours or by that same day. 

Q. What factors could affect how quickly I get my MRI report? 

There are many factors that can affect the time to prepare an MRI report including what type of scan it was, the total number of images, the radiologist’s workload, if it needs specialist review, and the urgency of the case. 

Q. How will I be notified when my MRI report is ready? 

Usually the radio report is sent to the referring physician and the physician will discuss the results with you. Some Imaging centers will provide patient reports through their online access.

Magnetic resonance imaging (MRI) is a non-invasive method of medical imaging that is widely employed in clinical practice. MRI utilizes a powerful magnetic field, radio waves, and advanced digital processing to produce pictures of internal structures. In particular, head MRI scans are a vital method for diagnosing and managing many medical conditions. Head MRI scans help clinicians visualize the brain, surrounding tissues, and vessels accurately.  

The following article provides substantial information on how head MRI scans work with a full review of indications, procedure, and performance of this important diagnostic investigation.  

Indications for Head MRI Scans 

There are numerous conditions for which a doctor might order a head MRI scan. Common conditions that may require the use of head MRI are the following: 

Headache – Headache is a common symptom afflicting individuals with various medical conditions, including migraines, sinusitis, and brain tumors. A head MRI scan may identify the reason for the headache, and in turn provide information to guide the treatment. 

Traumatic Brain Injury – A head MRI can be used to identify the degree of a traumatic brain injury (TBI), as well as to monitor the patient’s progression of recovery. 

Seizures – Seizures arise from irregular electrical activity in the brain, and there are many medical conditions that may result in seizures. A head MRI scan can be used to identify the reason for the seizures and provide treatment options. 

Tumors – A head MRI scan can identify the presence of brain tumors as well as their size, location, and type. 

Strokes – A head MRI can also provide evidence of a stroke, including a blood clot or bleed in the brain. Early detection is important so that an injury can be minimized and managed as best as possible. 

Multiple Sclerosis – Multiple sclerosis is a type of chronic disorder of the nervous system. MRI scanning can identify the abnormal lesions that appear in the brain and spinal cord. 

Preparation for a Head MRI Scan 

Before the MRI scan, the patient is asked to remove all metal from their body, including jewelry, watches, and hearing aids. These metal items may move or become heated because of the magnetic field of the MRI machine and thus pose a danger.  

If required, the patient will need to change into an additional gown from the diagnostic centre. The patient may also be given a mild sedative to help with relaxation if they are claustrophobic or are nervous about the scan. 

Throughout the Head MRI Scan 

Preparation: When everything is ready for the patient, they will be asked to lay down on a thin table which would be put into the MRI machine. The MRI machine is very large and shaped like a tube. The magnetic field is many times stronger than the Earth’s magnetic field. 

Communication: The MRI tech will be using the intercom system to speak with the patient and let them know what is happening throughout the scan. The patient will need to hold as still as possible during the scan because any movements can cause blurring. 

During Scanning: The MRI machine will make a loud thumping noise during the scan. The patient may be given earplugs or head which will help to drown out some of the noise. Alternatively, they will be allowed to listen to music or an audiobook to pass the time. 

Time: The scan can take anywhere from 30 min up to an hour depending on the images needed. If the patient is getting multiple scans, the patient may have to change positions between scans. 

Contrast agent injection: If a contrast-enhanced MRI has been ordered by the patient’s health care provider, than they will receive an injection of a contrast agent before the scan. The contrast agent will help eliminate some of the overlap of structures in the brain and improve the overall quality of the image. 

After the Head MRI Scan 

After the scan is completed, the patient can change back into clothing and resume their normal activity. There are no restrictions on diet or activity after a scan, and the patient will typically be able to drive home, or go back to work, right after the scan. 

The images taken during the scan will be sent to a radiologist, a specialist in interpreting medical images, who will study the images and send a report back to the healthcare provider who ordered the scan. 

Risks and Side Effects of Head MRI Scans 

Head MRIs are safe in most instances, and the magnetic fields and radio waves do not appear to cause any known harm. Here are a few common things to keep in mind:  

Claustrophobia – The small enclosed space of the MRI machine may be confusing or frightening for everyone, but especially for individuals with claustrophobia. If the patient begins to feel anxious or claustrophobic, they may ask for a mild sedative to calm them down.  

Gadolinium Contrast Agents – Contrast agents may trigger an allergic reaction in rare cases. An allergic reaction can manifest as hives, itching, and shortness of breath. If the patient gets any such symptoms during or directly following the MRI scan, they need to tell the MRI technician immediately.  

Metal Implants – Certain patients with metal implants, like pacemakers, cochlear implants, etc., cannot have an MRI scan. The metal can be jostled or even heated with the strong magnetic field and could become a dangerous situation.  

Noise – The MRI machine makes loud thumping and tapping noises during the test. Patient will be given earplugs or headphones to wear over their ears to eliminate damaging sound.  

Anxiety – The patient might be anxious or claustrophobic while in the machine, technicians will work with them if they feel they need a break or if they need a mild sedative if they are anxious or uncomfortable from being in the machine.  

Conclusion 

A head MRI scan is a non-invasive imaging procedure that uses a strong magnet and radio waves to generate images of the brain, blood vessels, and other soft tissues. It is done to diagnose various medical conditions including tumors, strokes, damage from a traumatic brain injury, etc. 

Before the scan, the person being examined will be asked to remove any metal from their body and to change clothes into a hospital gown. The person being examined will then be asked to lie on a narrow table and remain still inside the MRI machine. This can be noisy or uncomfortable for some individuals and will make them anxious or scared. The head MRI may take from 30 minutes up to a full hour depending on the images needed. 

Head MRI scans are considered safe in most circumstances; although patients with certain media-assistive implants will typically not be able to undergo this scan. Allergic reactions are rarely associated with the use of a contrast agent. In a small subset of adults patients will feel anxious or claustrophobic; this may complicate the situation by being unable to abide the request to stay still during the scan. 

If you are scheduled for a head MRI scan you should reliably follow the preparation instructions written by your physician, disclosing fully any implanted devices and informing them of the nature of your health conditions.
