Although spinal MRI studies are typically safe, there are some possible adverse effects: allergic reactions (if contrast dye was used), claustrophobia, and discomfort from the noise produced by the procedure. The likelihood of side effects from spinal MRI studies is small and (although very, very unlikely) a small number of devices can be affected by the strong magnetic field. In addition, there may be a risk of kidney problems with some contrast agents.
Possible side-effects from an MRI scan
MRI scans do not involve X-rays, therefore any of the possible concerns associated with X-ray images or CT scans (which use X-rays) are not associated with MRI scans.
There are rare instances where an individual may have a reaction to the contrast agent that is sometimes utilized.
Pregnant women are typically advised not to have an MRI, unless essential. Although it is deemed safe, little is known regarding the longer term implications of the strong magnetic fields on a developing baby.
What is the method behind an MRI scan?
Your body has millions of hydrogen atoms. When you step inside an MRI scanner the following happens:
- A strong magnetic field aligns particles called protons which are a part of the hydrogen atoms. All the protons align parallel to the magnetic field, like tiny magnets.
- The radio waves knock the protons from their orientation.
- While the protons are realigning back to their original position, they emit radio signals.
- The protons in various tissues of the body realign at differing speeds. Therefore, the emitted radio signals from different body tissues vary.
- These radio signals are detected by a receiver in the scanner.
- The receiver sends the radio signals to a computer.
What to expect after the MRI scan?
There are no after effects from the scan, and you can return to normal activities straight after the scan.
It is normal to wait for more weeks before hearing anything about your results. You will only hear about urgent findings sooner than that a radiologist will speak to a doctor before you hear about these. The result belongs to the person who requested the scan a hospital consultant will give you your results at your next appointment.
Claustrophobia and Anxiety
The number one fear from an MRI scan experience is claustrophobia or anxiety. The machine is designed to make patients lie still inside a narrow, tube-like structure for a while. The enclosed space can be difficult to deal with for many, especially those with enclosed space issues.
Noise Discomfort
MRI machines can make loud sounds while the scan is happening which can feel distracting and uncomfortable for some patients; as the magnetic fields switch on and off, they generate noise. The MRI machine is loud when it is switching; this is normal for the MRI.
If you have claustrophobia,
They’ll have solutions like sedation, anti-anxiety medication, or maybe an open MRI machine that is less restrictive. Listening to music or having someone in the room may also help you feel less anxious.
Alternative Solution: Most MRI centers will either supply earplugs or headphones to assuage the noise, or they will provide you the chance to bring music or audio book to listen to during your MRI to distract from the noise.
Gadolinium Allergy
Improvement solution: If you have a history of having an allergy or felt you had an allergic reaction with a contrast material, take that information to your provider. They can run a pre-scan allergy test, or they may elect to use a different imaging approach. Allergic reaction symptoms can include hives, itching, nausea, and infrequently trouble breathing.
Resolution Solution: Informing the MRI Technician of any discomfort, and they may provide a pad/cushion or reposition you slightly to relieve the pain.
Conclusion
Undergoing a spinal MRI is a safe, non-invasive scan that uses magnetic fields and radio waves (not ionizing radiation) to obtain diagnostic images. Most people will have no side effects from having an MRI, although, individuals may have some negative short-term experiences (such as some anxiety surrounding having it done, the noise of the scanning machine,
Frequently Asked Questions
Q. What organs does a thoracic MRI show?
A thoracic MRI is used to visualize primarily the thoracic spine, spinal cord, and soft tissues surrounding these structures.
Q. What will the MRI of the thorax show?
The thorax MRI is a highly detailed imaging study that provides precise images of the thoracic cavity structures, which include the mediastinum, chest wall, pleura, heart, and blood vessels, and is able to recognize numerous anomalies.
Q. When is a thoracic MRI needed?
A thoracic MRI is generally used after failed or persistent severe symptoms in the middle back area of the spine like pain, numbness, or additional neurological symptoms.
Q. Can a thoracic MRI show lung cancer?
MRI tends to follow along behind for a variety of different reasons, with only a few specific situations where it could provide more clarity than CT.
Q. Where to get the best MRI scan of the brain?
You can opt for carebox, to get your MRI scan of brain done.
