Is an MRI scan dangerous for the brain?

An MRI scan itself leaves no lasting impact on the brain. Exposure to the magnetic field has demonstrated zero interference with patient neurological function during the actual duration of the procedure. What can potentially cause issues is the contrast agent, should its use be deemed necessary. However, it is absolutely essential to conduct baseline biochemical screenings, specifically checking creatinine and urea levels. These serve as vital indicators of renal function; since the contrast medium is excreted via the urine, it must not be administered if these results fall below an acceptable threshold.
