What is MRI
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.
The images can then be examined on a computer monitor, printed or
copied to CD. MRI does not use ionizing radiation (x-rays).
Detailed MR images allow physicians to better evaluate various
parts of the body and certain diseases that may not be assessed
adequately with other imaging methods such as x-ray, ultrasound or
computed tomography
What are some common uses
of the procedure?
Sample image: MRI of the abdomen showing liver and kidneys -
frontal (coronal view)
MR imaging of the body is performed to evaluate:
- organs of the chest and abdomen—including the
heart, liver, biliary tract, kidney, spleen, and pancreas and
adrenal glands.
- pelvic organs including the
reproductive organs in the male (prostate and testicles) and the
female (uterus, cervix and ovaries).
- blood vessels (MR Angiography).
- breasts.
Physicians use the MR
examination to help diagnose or monitor treatment for conditions
such as:
- tumors of the chest, abdomen or pelvis.
- certain types of heart problems.
- blockages or enlargements of blood vessels,
including the aorta, renal arteries, and arteries in the legs.
- diseases of the liver, such as cirrhosis, and
that of other abdominal organs, including the 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 (e.g., uterus, ovaries, testicles,
prostate).
- causes of pelvic pain in women, such as
fibroids, endometriosis and adenomyosis.
- suspected uterine congenital
abnormalitynomalies in women undergoing evaluation for
infertility.
- breast cancer and implants.
