Magnetic Resonance Angiography
Medically reviewed by Drugs.com. Last updated on May 4, 2025.
Magnetic resonance angiography (MRA) is a test that uses magnetic fields and radio waves to take pictures of your blood vessels. An MRA can be used to look for a blockage or narrowing of blood vessels. It can also be used to check blood flow through your heart. An MRA can help your healthcare provider diagnose or treat a medical condition. It does not use radiation.
