If you or someone you love has had a blood clot, stroke, heart disease, or similar health problem, your doctor may recommend a magnetic resonance angiography (MRA) exam. Similar to magnetic resonance imaging (MRI), an MRA is a test that allows your doctor to view inside the body. More specifically, an MRA helps your doctor review the condition of your blood vessels.
