An MRI (Magnetic Resonance Imaging) scan uses magnetic fields and radio waves to create images of the body's internal structures, such as muscles, bones, fat and organs. It can help doctors diagnose a variety of conditions, including brain tumors, spinal cord injuries, strokes, and arthritis. An MRI scan is considered one of the most accurate diagnostic tools available today.
