A magnetic resonance imaging (MRI) scan is a common procedure around the world.

An MRI scan uses a large magnet, radio waves, and a computer to create a detailed, cross-sectional image of internal organs and tissues within the body. The following are examples in which an MRI scanner would be used:

•     anomalies of the brain and spinal cord

•     tumors, cysts, and other anomalies in various parts of the body

•     injuries or abnormalities of the joints, such as the back and knee

•     certain types of heart problems

•     diseases of the liver and other abdominal organs

•     the evaluation of pelvic pain in women, with causes including fibroids and endometriosis

•     suspected uterine anomalies in women undergoing evaluation for infertility
