What are the side effects of an MRI scan

Risks of Magnetic Resonance Imaging (MRI)

A Magnetic Resonance Imaging or MRI scan utilizes radio waves, magnets, and a computer to create pictures of the body’s internal organs. A huge, spherical magnet surrounds a tube that houses an MRI scanner. A mobile bed that may be fitted within the magnet is used to support the patient. The hydrogen atoms’ protons are aligned by the magnet’s powerful magnetic field before being subjected to a radio wave beam. The body’s protons spin, as a result, producing a weak signal that the MRI scanner’s receiver section may pick up. A picture is created by a computer processing the information from the receiver.

 What are the applications of an MRI?

When additional testing is insufficient to validate a patient’s diagnosis, an MRI scan in Chandigarh is frequently employed as an incredibly accurate way of illness detection throughout the body. Trauma to the brain might manifest in the head as bleeding or edema. Brain aneurysms, strokes, brain tumors, as well as tumors or inflammation of the spine, are other abnormalities that are frequently discovered.

What are the MRI’s potential hazards and adverse effects?

An MRI scan is a painless radiological procedure that has the benefit of reducing exposure to x-ray radiation. An MRI scan has no known negative consequences. The advantages of an MRI scan in Faridabad are related to its pinpoint precision in spotting bodily structural problems.

Patients who have metallic items in their bodies must provide this information to their doctor or the MRI team before the examination. The pictures produced by the MRI scanner can be considerably altered by metallic chips, materials, surgical clips, or other objects. The chance that the magnet will damage any heart pacemakers, metal implants, or metal chips or clips in or around the eyes prevents patients from having an MRI.

The patient lies still within the magnetic tube during the MRI scan. Some individuals may feel claustrophobic while having the surgery done. Patients should thus inform the doctor who is ordering the test and the radiology personnel if they have ever experienced claustrophobia. Before the MRI scan, a small sedative can be administered to aid with this discomfort. The MRI team from Atulya Healthcare will typically be present during the scan. Additionally, if the patient is unable to handle the scan, there is typically a way for them to contact the professionals (such as a bell they are holding).

How should I get ready for an MRI? How is it carried out?

Before getting an MRI scan, the body is free of any metallic items. On rare occasions, sedative drugs will be prescribed to patients to relieve their worry and help them rest throughout the MRI scan. For optimum accuracy, the patient must lay motionless throughout an MRI scan in Jammu. Inside the magnetic machine, patients recline in a secure space. Patients are instructed to relax and breathe normally throughout the process. Throughout the exam, communication with the MRI technician is maintained. Throughout the exam, as the scanner moves along, there are loud, repeating clicking noises. Patients may need intravenous liquid injections to improve the photos that are taken.

Usually, other than learning the procedure and establishing your expectations, there won’t be much you need to do to be ready for your scan. You might need to take off any jewelry or medical equipment that contains metal because magnetics will be used. The magnets may alter their location and function. Inform your physician and radiologist in advance if you are unable to remove an object so they can decide the best course of action for you. You will lie on a tiny bed that slides into the scanner, which is a big metal tube when it’s time for your scan.

The dangers of an MRI

There is no known danger associated with having an MRI scan at a respected Atlanta imaging facility once all medical devices are taken into account and anxiousness is under control. Exposure is not a worry because the scan does not use radiation like an x-ray. If you do need a nerve-soothing drug, talk to your doctor about any possible adverse effects. A very small possibility of a response to the contrast dye is also present.

There are no aftereffects of the scan, and you should be able to carry on with your day as usual unless you were sedated. The major disadvantage is the lengthy 30-90 minute standard MRI procedure.

Oral Adverse Reactions

For gastrointestinal tract MRI scans, oral GBCAs are occasionally employed. They are ingested in liquid form before the scan. The contrast agent commonly consists of mannitol and a kind of gadolinium called gadolinium-DPTA (a type of sugar alcohol that is poorly absorbed by the intestines).

Some people have experienced nausea, vomiting, and diarrhea after consuming mannitol. While gadolinium may be administered alone with little to no gastrointestinal adverse effects, it requires mannitol to be stable in the stomach’s and intestines’ acidic environments.

Permanent Security

The debate over GBCAs’ long-term safety is still open, especially when they are often or intensively used (such as when monitoring multiple sclerosis).

The FDA released a safety alert in 2015 citing research showing that extended gadolinium treatment in MS patients led to metal deposits in the brain tissues.

Recent studies indicate that the danger of accumulation is dose-dependent, indicating that the risk increases with the duration of gadolinium usage. For those who have been exposed to GBCAs just once or a few times, the danger seems to be minimal. The FDA advice omitted to include if there are any health hazards associated with the deposits.


It is fair to inquire about the necessity of the contrast agent if a healthcare professional advises a contrast-enhanced MRI. Contrast may be necessary for some reasons, but it’s reasonable to wonder whether there are any alternative possibilities.

This is especially true if you have a renal illness that is well-known to you or if you have had several contrast-enhanced MRIs. Don’t be afraid to get a second opinion if you’re unsure about the best MRI scan center.
