Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

MR imaging uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. Images can be examined on a computer monitor, printed or copied to CD. MRI does not use ionizing radiation (X-rays).

Detailed MR images help physicians evaluate parts of the body and certain diseases that may not be adequately assessed using X-ray, ultrasound or CAT (computerized axial tomography) scan.

MR imaging of the body evaluates:

Organs of the chest and abdomen including the liver, biliary tract, kidney, spleen, pancreas and adrenal glands
Pelvic organs including reproductive organs in the male (prostate and testicles) and the female (uterus, cervix and ovaries)
Blood vessels (MR angiography)
Breasts

Physicians use MR examination to help diagnose or monitor treatment for:

Tumors of the chest, abdomen or pelvis
Blockages or enlargements of blood vessels, including the aorta, renal arteries and arteries in the legs
Diseases of the liver, such as cirrhosis and other abdominal organs, including bile ducts, gallbladder and pancreatic ducts
Cysts and solid tumors in the kidneys and other parts of the urinary tract
Tumors and other abnormalities of the reproductive organs (uterus, ovaries, testicles, prostate)
Causes of pelvic pain in women, such as fibroids, endometriosis and adenomyosis
Suspected uterine congenital abnormalities in women undergoing evaluation for infertility
Breast cancer and implants
