What is an MR Angiography?
MR angiography (MRA) uses a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities or diagnose atherosclerotic (plaque) disease. This exam does not use ionizing radiation and may require an injection of a contrast material called gadolinium, which is less likely to cause an allergic reaction than iodinated contrast medium.
What are some common uses of the procedure?
MRA is used to examine blood vessels in key areas of the body, including the:
- Brain
- Neck
- Heart
- Chest
- Abdomen (such as the kidneys and liver)
- Pelvis
- Legs and feet
- Arms and hands
