Magnetic Resonance Angiogram (MRA)

MRA (Magnetic Resonance Angiography)

Why It Is Done

A magnetic resonance angiogram (MRA) is done to look for:

• A bulge (aneurysm), clot, or the buildup of fat and calcium deposits (stenosis caused by plaque) in the blood vessels leading to the brain.
• An aneurysm or tear (dissection) in the aorta, which carries blood from the heart to the rest of the body.
• Narrowing (stenosis) of the blood vessels leading to the lungs, kidneys, or legs.
