This can be, but is not limited to: contrast MRI, functional MRI (fMRI), cardiac MRI, musculoskeletal MRI, and likely a handful more. MRI scans are not new and have been in use with medical professionals for the diagnosis of illnesses, ranging from head trauma to heart health. MRI scans usually yield more management information on a patient, and how one may gauge or establish surgical prognosis. 

Types of MRI Scans

Bones and Joints MRI’s- A bone MRI is utilized to observe whether an individual has spinal disc issues and tumors in soft body parts and bones as well.

Internal Organ MRI’s- Can confirm the existence of tumors in most organs such as kidney and pancreas and even lymphatic organs. Can confirm tumors in the reproductive organs such as uterus and ovaries.

Breast MRI- A breast MRI can also be utilized to follow up on breast cancer lesions for change, or to check for a leak from silicone implants.

Magnetic resonance angiography–  This is an MRI that focuses specifically on the blood vessels and blood flow in the body. An MRA may be used to see why a blockage or narrowing occurred in the blood vessels, or why a stroke occurred.

Cardiac MRI’s – This technique examines the heart anatomy such as the size of the heart chambers and the thickness of the heart wall. It is also able to determine the degree of damage of heart disease and the damage of a recent myocardial infarction.

Brain and Spinal Cord MRI’s- The imaging method most frequently utilized to assess cerebral vessel aneurysms, eye and inner ear issues, and spinal cord issues. It can also assess any brain trauma.

Functional MRI’s- Used to illustrate the structure of the brain and distinct sections of the brain that control many of a body’s functions, e.g., movement or language.

MRI scans are not necessary in all cases. Some MRI scans need the administration of contrast material. This makes it easier to get high-quality imaging while scanning. Depending on whether there is a tumour, infection, or inflammation in vessels or other organs, better visualization of them will be possible.

Conclusion 

MRI is becoming increasingly available to a variety of specialties, as it has a uniquely broad number of types of MRI scans and applications.  MRI will remain a part of personalized medicine as it brings tangible improvements to patient outcomes through tailor-made, accurate, information-rich, non-invasive imaging from diagnosing diseases that change lives.

MRI (Magnetic Resonance Imaging) functions properly when using a strong magnetic field and radio waves to make detailed images of the body’s internal structure. The major process is accomplished by using the magnetic field to orient the hydrogen atoms in the body, then the same magnetic energy is used to create a radio wave exciting the hydrogen atoms, finally as the hydrogen atoms relax back to their original position, energy is sensed and used to produce an image.

Basic Principles Are- 

We are all composed of cells that contain water, which contains hydrogen ions (H2O). The magnetic field’s strength and polarity can be changed, therefore it can effectively restrict a change in the proton’s “spin” during which we can construct layers of information. Precession describes the way protons will return to their initial state when the magnet is turned off. Put simply, different tissue types in our bodies will recover at different conditions, and that’s how we see or differentiate the different tissues in the body.

Reclamation and Signal Detection: 

When magnetic radio waves are turned off the protons will relax back to their inherent state while releasing energy in the form of radio waves. The MRI machine detects this energy and sends the signals to a computer where they are interpreted. 

Image Generation: 

The nature and state of the proton environment and type of tissue determine the nature and intensity of the signals we observe. Each of the numerous tissues and structures within the body has a different relaxation time, the MRI machine will generate complex images of each distinct tissue because of its ability to separate the various tissues.

Computer Processing:

The received signals are converted into digital signals in the form of an image that can be displayed on a computer monitor, or printed.  The computer will then use advanced algorithms, synthesize the data, reconstruct an image, and the image is dished up to the user to examine and interpret the internal organs and internal tissue of the patient. 

Essentially, MRI exploits the natural magnetic properties of the body to produce a diagnostic image with a whole lot of ease and detail, and without any use of ionizing radiation as with X-ray imaging. 

Strong Magnetic Fields:

MRI machines generate a strong magnet, creating a very strong magnetic field.

This magnetic field aligns the magnet moments of hydrogen atoms (protons) in your body which causes those protons to spin in an aligned manner.

Radio Frequency Pulses:

The MRI machine next sends radio waves which excitates or gives energy to the protons.  The radio waves are at the correct frequency to flip the aligned protons out of equilibrium.

Conclusion

The magnetic field acts on the probe or protons when they are at the equilibrium condition. Is then delivered to the patient to disrupt or perturb the equilibrium condition with a highly controlled energy called a radio frequency pulse. The radio frequency pulse will excite the protons into another orientation that is not aligned with the magnetic field direction. The radio frequency pulse is very short, and there is then a time interval for the protons to relax back to equilibrium.

When proton relaxation brings them back to homeostasis (in a direction aligned with the magnetic field) the protons will emit signals which can be detected by computational coils producing an analogue signal. These analogue signals are then put through A/D (analogue/digital) converters sending digital data to the computers. 

Since all tissues in the body have unique properties about returning to homeostasis, MRI can be used to distinguish between tissue types. 

MRI can program changes in magnetic field strength ,and radio frequency pulse sequence to produce images either T1 contrast or T2 contrast based.

Frequently Asked Questions

Q. What is the mechanism of the MRI?

Most protons, which are typically randomly aligned in the nuclei of water in biological tissue, are aligned by a strong, stable external magnetic field.

Q. Why is MRI so loud?

Most of the characteristic sound heard from an MRI scan is caused by the changes of the magnetic fields of the gradient coils at high rate.

Q. Why can’t you drink water before an MRI?

Water is usually permitted before MRI scan but please follow the instructions.

Q. What is not allowed during MRI? 

An MRI has a large magnetic field that will not allow the following items into the room: the vast majority of metal objects such as jewelry, watches, credit cards, etc; electronic devices such as cell phones, hearing aids, and other devices. 

Q. How to pass time during MRI?

To help make the time go more lickety-split in an MRI, you might want to think about relaxing, distraction, and focusing on positive things. You might want to think about guided meditation, happy music, or letting your mind wander to positive images or stories.

CT scans on the hand are generally safe, but there are some side effects such as radiation exposure, allergic reaction to contrast dye, exposure to radiation is low, but theoretically it might increase your chances of getting cancer in the long run particularly pregnant women and children. Reactions can be mild Discomfort may be from lying flat to have the scan or from receiving contrast dye injection.

Allergic Reaction to Contrast Dye

Allergic reactions (though rare allergic reactions will occur) will occur if dye is in a CT scan. Reactions may be slight (hives, redness, and itchiness) or major (wheezing, having trouble breathing, and/or anaphylactic shock). It is better to report a reaction to contrast sooner than it is to report any allergies or medical conditions that would apply.

Radiation Exposure

Hand CT scans, like all CT scans, employ the use of ionizing radiation that carries some small risk of long-term complications, most commonly cancer. In general terms, the patient dose from one CT scan is very small, and the capability to deliver an accurate diagnosis may outweigh.

Discomfort

There is a small level of discomfort with a CT scan of the hand since the radiographer will ask you to be completely still for several minutes at a time. If they are using contrast dye you may get a passing sensation of heat wash over your body or sense a metallic taste. 

Possible Complications

The contrast dye may potentially impair kidney function in certain individuals with kidney problems.A CT hand scan involves a tiny dose of ionizing radiation (as does any CT scan), which can contribute somewhat to cancer risk, especially with repeated scans. If you are given

Pregnancy

A CT of the hand during pregnancy is very low risk to the baby when the CT is not of the pelvis or abdomen. Although a CT does give off radiation, the radiation dose and exposure from an adult hand CT are minuscule and are very low, and are many times considered acceptable risk versus the possible benefit of diagnosing an illness that it is necessary.

Weight Limitations

Similar to all CT scans, CT hand scans have size and weight limitations with regard to the patient. The size of the opening of the scanner can be limiting as well. Patients larger than the maximum weight limitation and gantry opening limitation will typically not be scanned. 

Previous Reactions

The most frequent adverse effects are transient and mild but may include severe reactions that always include the contrast. 

Conclusion

It is probably safe enough for you to have a CT scan of your hand since it has low radiation dose and few side effects. You should bring to your doctor’s attention the following risk factors, in rare situations, mild allergic reaction to the contrast dye during the CT scan, and mild discomfort when you have the CT scan, and in rare situations, an effect on the kidney, and severe allergic reactions in rare situations.

Frequently Asked Questions

Q. Are there any harmful side effects of CT scan?

Of course, it is risky. CT scans are proven to be safe because they also have some risks with a CT scan.

Q. Can you provide me with a CT scan on my hand?

Yes,CT hand scans are an extremely effective method of examining the bones, joints, ligaments, tendons, and soft tissue to check whether there is any malfunction in the hand.

Q. To whom should CT scans be avoided?

Children below the age of 18 years, women in pregnancy, patients with incomplete medical history, and patients with allergies should usually avoid, or at least utilize, CT scans.

Q. How to get rid of radiation after a CT scan?

You don’t need to actively eliminate radiation after a CT scan because the radiation isn’t deposited in your body. CT scans involve X-ray radiation; the radiation goes through your body during the scan, and therefore theoretically there shouldn’t be any residual radioactivity.

Q. For how long will the side effects of a CT scan persist?

The majority of the side effects of a CT scan are transient and mild in nature which most likely resolves within several hours. Some of the possible side effects are fatigue and headache, which generally improve within 24-48 hours following a CT scan.

FNAC is not the new phrase in medical diagnosis but it is the technique which has been employed from long now to identify different conditions of lumps, swelling, infection and other conditions which are required to be identified. 

FNAC is the abbreviated term for fine needle aspiration cytology which involves aspirating a small sample of affected area and examining it under microscope for the pathogen of the condition. There are different conditions which are identified by the FNAC test and these are cancer, infections, inflammatory conditions etc. FNAC test is very minimally invasive and has a high diagnostic rate that assists patients in identifying conditions without undergoing any surgical procedure. 

What is the FNAC Test?

FNAC is the abbreviation of a medical process named Fine Needle Aspiration Cytology.

The procedure is fast, cost-effective and minimally invasive to check the different conditions. Such conditions include lumps, masses, swelling and nodules in the body and aid in detecting the condition without seeking any large scale surgical procedure for detection of abnormality. There are certain regions of the body particularly the thyroid, breasts, lymph nodes and salivary glands where this procedure is useful for identifying abnormality. 

This procedure is simple and does not require any diagnostic tool. A simple hollow needle is used for the process, and it is done at the place of concern. The slide will be reviewed by a trained pathologist and confirm the diagnosis. This process is useful in diagnosing conditions including cancer, infection, and inflammation of the region etc. 

FNAC Test Full Form and Meaning

FNAC stands for Fine Needle Aspiration Cytology, which is the investigative test employed to search for a range of conditions. This is a simple and cheap process which can identify the reason behind lumps, swellings and other illnesses which may be the cause of some chronic illness.

FNAC test means the diagnostic or testing procedure used to investigate cells from any offending tissue. The cell lumps help identify if it is cancerous (malignant) or not cancerous (benign).

FNAC is provided by doctors to initially check the new lumps for early diagnosis that helps in a fast identification of abnormality.

Purpose of FNAC Test

FNAC test is advised for numerous reasons:

• To rule out or confirm cancer.
• This test aids in the planning of treatment according to diagnosis.
• This aids in planning surgery for the condition.
• To assess familiar lesions which have altered size or texture.

FNAC Test Procedure

The FNAC procedure for the assessment of the lesion is easy, quick, cheap, painless and reliable.

The first stage is preparing the patient for the test, including cleaning the skin around the prick with antiseptic.

The second stage is the act of inserting the needle into the lesion, swelling or abnormal area needing to be tested and aspirating and or obtaining cells or fluids for the sample.

The third stage is to put the sample obtained, or smear, on the glass slide for diagnosis. The slide is examined under the microscope, seeking to determine whether or not there is any abnormality.

The fourth stage is the final stage, where the glass slide is examined by a qualified, experienced pathologist under the microscope, seeking any abnormality.

In total for FNAC testing, the cover to cover process will take approximately 15-20 minutes and the patient can return to his/her normal routine.

FNAC Test for Breast

FNAC test is the most prevalent test applied for breast diagnosis and abnormalities. There are numerous breast-related conditions that can be diagnosed by breasts and are as follows:

FNAC test assists to identify breast cancer in initial stages of infection.

This test of diagnosis assists in differentiating the solid tumors or cysts filled with fluids.

This also assists in directing the treatment prior to going for any form of treatment.

This test also assists in imaging the body’s conditions.

FNAC Test Price

The price of the FNAC test is mostly affordable:

price of FNAC test is approximately Rs. 1000 to Rs. 3000. This test is also based on several conditions regarding the price aspect and these are:

Location of Diagnostic lab

Whether the laboratory is private or government

FNAC Test Normal Report

A FNAC test normal report normally indicates that the cells in the sample appear healthy and have no traces of malignancy or infection. The report is used to ascertain if the lump is malignant or benign. Although with a normal report, doctors may advise follow-up in case the lump continues or alters overtime. 

What is the meaning if my FNAC Test is Positive?

Positive report of FNAC test indicates that the cells are malignant and requires further analysis to search for the extent of disease. Some of the diagnostic tests which aid to diagnose the disease at large are imaging tests, biopsy tests, surgeries etc.

Benefits of FNAC Test

• Rapid and less invasive.
• No hospitalization is required.
• Low cost.
• Premature immediate results.
• Averts unnecessary surgery.

Conclusion

The FNAC test is the acronym of Fine Needle Aspiration Cytology test that is one of the fastest and utmost test used to look into lumps, swellings, infection etc. This is the preferred test as physician can prescribe the same in case of suspected any cancerous behavior in lumps, swellings or infections in the area. 

This test is done through sample extraction from the swellings or fluid containing cells and afterwards spread over slide in order to seek the infection. After sample spread on slide, a pathologist will search for any kind of abnormality in the sample and will prepare the results accordingly.

MRI in the healthcare community has transformed the process of diagnosing and managing musculoskeletal disease. MRI is unique in that it is possible to obtain images of structures at excellent resolution and is non-invasive. MRI has been of great worth to healthcare systems and patients over the last few years due to the actual need for this imaging modality as increased demand has continued to rise. This blog post will critique the use of MRI in musculoskeletal and medical imaging in general, clinical applications, MRI technology developments, and future perspectives. 

Clinical Relevance of MRI in Musculoskeletal Imaging

MRI is relevant in MSK imaging due to its capacity for producing images that offer higher contrast and resolution to show soft tissue and anatomy in detail. MRI, unlike X-ray or CT imaging, does not employ ionizing radiation making this a safer option to use overall, and in certain vulnerable groups in particular (children and teenagers). MRI is a highly effective method to evaluate large joints, spine, and extremities – and is therefore the gold standard for diagnosing an enormous range of conditions. 

General Clinical Indications Include The Following

• Joint Disorders: Imaging degenerative joint disease, meniscal tears, ligamentous injuries, and labral tears in the hip and shoulder.

• Spinal Diseases: Imaging herniated disks, spinal cord integrity after trauma, congenital idiopathic scoliosis, etc.

• Soft Tissue Injuries: Imaging muscle, tendon, and ligament injury including sports injuries and repetitive strain.

• Bone & Tumor Evaluation: Fracture evaluation (such as occult fractures), osteomyelitis, and primary bone and soft tissue metastatic tumors, and soft tissue and bone primary tumors.

• Pediatric: Evaluation of congenital and developmental deformities in children.

Technological Progress Via Musculoskeletal MRI

Today, there is a tremendous amount of progress in the technology of MRI, particularly in recent years. Progress in MRI is progressing fast and, consequently, high field strength magnets and pulse sequences are available for providing quick scans with improved quality and diagnostic value compared to earlier. 

Impact on Patient Care

MRIs can obtain effective diagnosis of ailments that must be treated urgently. Timely diagnosis will enhance patient outcomes by virtue of their high-resolution imaging capability. MRIs, for example, can detect stress fractures and soft tissue injuries that go undetected on other modalities, allowing for immediate treatment and low risk for complications. 

Challenges and Future Directions

MRI will also be challenged by high cost, long scanning times, and the expense of specialized education.

Thankfully, scientists are still working on decreasing costs and scan time using low-field-strength magnets and artificial intelligence. With the development of synthetic MRI with and MR fingerprinting, MRI may become faster, and offer even more personalized imaging.

Conclusion

Even with this, MRI of musculoskeletal imaging has a unique amount of detail and safety in diagnosing and monitoring many disorders. MRI will remain at the forefront in MSK diagnostic imaging using technology advances to enhance patient care and outcomes.

Frequently Asked Questions

Q. What are the clinical indications that MRI is superior to x-ray or CT for soft tissue imaging?

MRI can evaluate soft tissue abnormalities like muscle, tendon or ligament tears and even slight soft tissue changes not detectable on x-ray or CT. MRI does not also expose one to ionizing radiation.

Q. How does MRI enable conditions/pathologies to be identified early?

MRI may allow for the early detection of conditions/pathologies stress fractures, trivial soft tissue injury, incipient arthritis before they present with symptoms, facilitating the early intervention of treatment and potentially better outcomes.

Q. For what reasons is MRI indicated in musculoskeletal imaging?  

MRI is valuable in musculoskeletal imaging to evaluate numerous conditions of the musculoskeletal system including pathology of joints, fractures, disk pathologies in the spine, athletic injury, tumors, and pain, swelling, or hemorrhages in tissues.

Musculoskeletal magnetic resonance imaging provides an important complementary investigation in diagnosis of numerous conditions related to bones, joints, muscles, tendons and ligaments. 

Q. Is MRI useful for treatment planning? 

Yes, MRI is beneficial for treatment planning, especially in radiotherapy, as it provides better soft tissue contrast and allows for improved delineation of the target volume and  organs-at-risk (OAR) than can be accomplished with CT alone. 

Do you have a stiff or sore neck? An ultrasound of the neck is a convenient option. It uses sound waves. The waves produce pictures of your neck. Doctors can examine key structures. Such as your thyroid gland. Veins and lymph nodes too.

It is harmless and painless to take a test. There is no radiation involved. It is therefore safe for most individuals. Pregnant women and even children can get it done.

What is a Neck Ultrasound Used For?

Physicians order neck ultrasounds for a number of reasons:

Thyroid Problems: It can examine the size and shape of the thyroid gland. It can identify nodules or cysts. These may require additional testing. Thyroid conditions are a common indication for a neck ultrasound.

Lymph Nodes: Sick lymph nodes may be enlarged. Or something. Ultrasound can quantify their size and shape.

Salivary Glands: Having trouble with your salivary glands? Ultrasound to the rescue. It can identify stones or tumors.

Blood Vessels: The carotid arteries on the front of your neck bring blood to your brain. Blockage or narrowing can be seen by ultrasound.

Lumps and Bumps: If you do have a lump in your neck, an ultrasound will inform you as to what the lump is. This will inform you whether it is a solid or fluid. Guiding Procedures: The needle is occasionally guided by ultrasound. This is for biopsies or draining fluid.

What to Expect When You Have An Ultrasound Scan Of the Neck?

There could be numerous things you will experience when you have your neck ultrasound scan; some could be from these, including:

The test itself is not long at all. It will only take 15 to 30 minutes. You will be on your back. Gel will be put into your neck. In this way, the sound waves can travel more easily.

Your skin will be wiped with a small device. The device is a transducer. It makes sound waves. These reflect off your neck tissues. The transducer receives the echoes. The computer translates them into images. These are shown on a screen.

You may be asked to turn your head. Or to hold your breath for several seconds. This will help get clearer pictures. Several pictures will be taken by the technician. They will select the most suitable ones to send to the physician to look at.

The gel is water. It is simple to take off. You can go back to what you were doing after the scan.

A magnetic resonance imaging of the spine is a painless test where you will lie inside a large, tube-like machine while the machine takes pictures of your spinal column and the soft tissue around it. 

Before The Scan 

Preparation: You will probably be asked to remove all metal items, including jewelry, watches, piercings and any clothing with metal details, because of the strength of the magnets used in the MRI.

Safety Measures: If you have certain medical implants such as pacemakers, cochlear implants, metal fragments, please tell the technician since some implants may not be safe for MRI. 

Contrast Material: In some instances, a contrast dye may be injected to clarify images, usually to see if there are tumors, infections, or inflammation. This will be done with an IV, and is usually painless though very rare allergic reactions do happen.

During The Scan

Noise & Movement: The MRI emits loud tapping or thumping sounds during the scanning process, as the magnetic fields are changing. 

Communication: The technologist will be in a different room; however, he or she can see, hear and talk to you during the entire scanning process. You will receive a “call button” 

Duration: The exam typically takes 30-60 minutes depending on how many areas are being examined and also if contrast is used. 

Sensation: The table may feel hard or cold which you may need extra pillows or blankets to feel comfortable on.

Post-Scan

Concluding: You will be able to get your clothes back on and go back to your regular activities immediately, except if you received an anxiety sedative (very rare).

Dye Side Effects: If you received contrast dye, you will be monitored for a brief time for a reaction most people have no reaction to.

Results: The images will be interpreted by a radiologist and a report is sent to your referring doctor. 

Conclusion

Most patients report that the MRI procedure is tolerable and that the temporary discomfort associated with the procedure is outweighed by the valuable information that they obtain from the MRI.In the end, the spinal MRI will give you and your doctor helpful information in trying to accomplish an accurate diagnosis and treatment for a variety of spinal conditions. 

Frequently Asked Questions

Q. How long does a spine MRI take?

The duration of a spine MRI takes anywhere from 30-60 minutes for most MRIs and will vary based on which area is being scanned (cervical, thoracic, lumbar) and whether or not a contrast dye is used to help enhance what she sees in the images.

Q. Is a spinal MRI painful?

Although there is no pain in the actual imaging, some people may feel discomfort from lying flat in one position for a prolonged period of time.

Q. What not to do before spine MRI?

Remember when you are getting a spine MRI, to completely undress of metal items, and to also have no metal items on your person.

Q. What happens if MRI results are bad?

If your MRI shows abnormalities, your next steps would be determined by both the degree of the abnormality and the type of abnormality. 

Q. How to know if MRI is abnormal?

An abnormal MRI result is characterized by changes in intensity or structure of the signal compared to what is considered normal for a given area, often compared to previous scans or baseline information. 

An MRI head scan is a painless exam that will take pictures of your brain and the surrounding structures inside your head using a strong magnetic field and radio waves. The exam typically involves you lying on a flat, moveable table that will slide you into a tube-shaped magnet. While the scan is running, you will hear some loud knocking or thumping noises. This is the scanner taking pictures. You will be given some sort of ear plugs or headphones. You will need to lie still through the scan so the pictures are not blurry. 

What Is a Head MRI?

An MRI of the head is a non-invasive procedure which scans the head and converts the information into a series of images. Those images can be used as tests to determine the cause of certain symptoms. 

An MRI scan or study is used to help diagnose a variety of conditions and to monitor a person’s response to treatment of an illness, injury, or other condition of the head. There is no pain associated with MRI.

How do I get ready for a head MRI?

The medical team will want to establish if you have any metal anywhere in your body, including:

• inner ear implants
• artificial joints
• defibrillator or pacemaker
• certain kinds of heart valves
• vascular stents
• brain aneurysm clips

The team will also want to confirm if you’d ever done work with sheet metal or had an injury with metal shrapnel. All of those items will affect your safety during the MRI. In the situation of implants and pacemakers, an MRI’s magnetic field could cause those items to not work correctly.

What is the process for a head MRI? 

The table will slide into a large magnet, which looks like a tube. After the table slides into the machine, the technician will take a series of pictures of your brain, each taking a few minutes. 

What to expect after a head MRI?

After the procedure, you can put your clothes on and leave the imaging center (if you were sedated for the exam, the staff may move you to a recovery room until you are awake – usually 1-2 hours after the sedative is given).

A radiologist will read your MRI scans and send the results to your doctor. If your head MRI was an emergency, your results will be quick. What happens next will depend on whether they found anything unusual and were able to confirm the cause of any abnormalities.

CONCLUSION

The ability to obtain accurate images from the MRI is following the preparatory information in the beginning and remaining still during the scan. The combination of all these factors will allow for meaningful measures of safe screening and monitoring options for doctors and patients alike.

Frequently Asked Questions

Q. How do you prepare for a head MRI?

Do not wear jewelry and wear loose fitting and comfortable clothing. You may be asked to wear a gown of your own, if so, it will be provided for you.

Q. How long is the head MRI procedure?

“30 to 60 Minutes”

Q. What is the procedure for a head scan?

If you are scheduled for a head scan (CT or MRI scan), you will only need to lay on a table that pulls the head part of the body into a tunnel-shaped machine. Usually, you lay still, which might include holding your breath for only a short period.

Q. What not to do before an MRI?

Please refrain from wearing or having on you anything metallic, including jewelry, hearing aids, or certain clothing with metal. Some people will either need to fast or take their medications based on the MRI type and their health problems.

Q. Can MRI results be seen immediately?

The images must first be evaluated by a radiologist a doctor who specializes in reading medical imaging – which takes a few days to a week. The radiologist writes a report to the referring doctor and the referring doctor is able to convey that report to the patient.

Sometimes small trace amounts retain in different body tissues including your brain, bones, or skin long after your scan. This is known as gadolinium retention. Retention is usually harmless in patients with normal kidney function, but may lead to nephrogenic systemic fibrosis in patients that are already in failure of their kidneys.

NSF creates an abnormal thickening and hardness of skin and underlying soft tissues. NSF can advance to the involvement of other muscles and organs, such as: the heart, lungs, or other muscles – and could potentially become life-threatening. NSF accumulation often produces several symptoms, including:

• Skin Changes: some text
• Swelling, hypertension, and hardening skin 
• Skin may feel woody and/or appear as if it has orange-peel like appearance
• Blisters/Ulcers/dormitories
• Difficulty moving muscles or joints
• Muscle weakness
• Yellowed eyes

Getting Ready for your MRI with Contrast

Discussing Your Medical History

Preparation with a full medical history is an excellent way to reduce the chance of an adverse effect. Have a conversation with your health care provider ahead of your procedure and make sure you do the full disclosure on all past adverse potential effects, allergies, kidney issues, and any other medical history that may be relevant, as they will direct you to the safest imaging choices available for your procedure based on your medical history. If you ever have concerns regarding an MRI contrast agent, do not hesitate to inquire with your health care provider regarding alternative choices (e.g., different contrast agent, MRI without contrast, or alternative imaging options such as CT imaging).

For most MRIs with contrast, you will likely be able to eat and drink without restrictions before the scan, but in some cases your healthcare provider may ask that you avoid eating and drinking for

four to six hours before having your MRI; again, this will be at the provider’s discretion

Before: You may have to have a blood draw to determine kidney function prior to MRI with contrast, especially if you have a history of kidney issues or diabetes. You may also have to be screened for allergies to rule out sensitivities to the contrast agent. Then the contrast will be administered either orally or intravenously.

During: Your MRI will take just 20 minutes to an hour depending on the body part being examined. While you are in the machine, the tech will be able to talk to you as needed through the intercom.

After:If you received contrast for your MRI, be sure to note any side effects you have and consult with a healthcare professional and report any concerns.

Conclusion

MRI scans with contrast generally have a good safety record, particularly in patients with normal kidney function, though there are serious rare risks such as nephrogenic systemic fibrosis and gadolinium retention that should be noted particularly in patients with renal issues. You can help ensure your imaging experience is safe, effective, and manageable by openly sharing your complete medical history, following the preparation directions, and reporting new symptoms or concerns, if any, after the exam as soon as possible.
