An MRI (magnetic resonance imaging) scan is a medical test that uses magnetic fields and radio waves to produce images of the inside of the body. It is used to diagnose many conditions, including brain tumors, strokes, spinal injuries, and other diseases or disorders. The procedure takes about 30 minutes and involves being placed in a machine that looks like a large tube. You will be asked to lie still while the machine does its work.
