Possible risks of MRI scan

 Without the use of x-rays or any radiation, Magnetic Resonance Imaging / MRI allows for the detailed imaging of organs and tissues throughout the body. A large, round magnet surrounds a tube that houses an MRI-compatible screen. An MRI-compatible camera that may be fitted within the magnet is used to support the patient. The magnet's powerful magnetic field presents the hydrogen atoms' protons before being subjected to a radio wave beam. The resolution and detail of an MRI picture are fairly high, and it is capable of detecting minute alterations in bodily structures. To improve the accuracy of the pictures during several operations, contrast chemicals like gadolinium are employed.

Risks associated with MRI Scan-

1.       If a ferromagnetic aneurysm clip is present, an MRI test will not be done since there is a possibility that the clip might move and seriously damage the patient.

2.        Patients that have metallic items in their bodies should inform their doctor or the MRI team before the scan takes place.

3.       It is assumed that the magnet may move the metal in these regions which prevent doctors from using MRIs on patients who have heart pacemakers, metal implants, or clips in or near their eyes.

4.      An external hearing aid, cardiac pacemaker, electrical stimulator, or neurostimulator might all be harmed or malfunctioned by the MR system's strong magnetic field.

5.        In order to enhance the information displayed on the MRI-compatible display during some MRI scans, a substance known as a gadolinium contrast agent may be injected into the patient's vein. This procedure is unusual, but it can occasionally result in an allergic response or other complications.

6.      The computer creates visual pictures of the body part that was scanned when the MRI scanning is finished. These pictures can be recorded on film. A medical professional with specialized training in reading body image is known as a radiologist. The doctor who requested the MRI scan receives the scan in the form of a report. 

7.      Prior to the MRI, a kidney function test may occasionally be required to ensure that your kidneys can effectively remove the contrast agent from your body. Let your doctor know if you have diabetes or renal issues so that no further problems take place.

8.      Some people are allergic to the contrast agent so in that case, some patients may become sensitive to it, so then MRI scan is not that easy to conduct.

Conclusion-

The above-mentioned assessments and measures should be taken before undergoing any MRI Scan. Depending on the exact medical condition you have, there can be additional concerns. Before the MRI scan, be sure to go over any issues you have with your doctor.
