Health risks are very rare with MRIs and MRAs. The FDA receives roughly 300 reports a year out of the millions of MRI scans performed.
Should you get an MRI every year?

Why would an MRI need to be repeated?
“The most common causes that lead to the repetition of MRI exams are the patients’ movement and the use of incorrect technical parameters by the diagnostic [radiologic technologists].”
How many MRIs can be done in a day?

An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images.
Is MRI better than CT scan?
Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
What are two major disadvantages of MRI scans?
Drawbacks of MRI scans include their much higher cost, and patient discomfort with the procedure. The MRI scanner subjects the patient to such powerful electromagnets that the scan room must be shielded.

Is MRI bad for your brain?
Risks. MRIs are safe and relatively easy. No health risks are associated with the magnetic field or radio waves, since the low-energy radio waves use no radiation. The procedure can be repeated without side effects.
