Magnetic Resonance Angiography produces images of blood vessels throughout the body and is commonly used to diagnose:
• Inflammation and aneurysms in the aorta or in other major blood vessels
• Atherosclerotic disease in the arteries of the neck, which may limit blood flow to the brain and cause a stroke
• Aneurysms or arteriovenous malformations in the brain
• An atherosclerotic disease that has narrowed the arteries to the legs
• To guide surgeons making repairs to diseased blood vessels, such as implanting or evaluating a stent
• Identify dissection or splitting in the aorta in the chest or abdomen or its major branches
The exact nature of the scan depends on the vessel that needs to be examined and the procedure varies accordingly.
