Magnetic Resonance Angiography


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.

  • Swelling of your mouth or face
  • Nausea or vomiting
  • Sudden decrease in urination

Contact your healthcare provider if:

  • You have pain or bleeding at the injection site.
  • You have signs of an infection, such as redness or swelling, at the injection site.

  • You have an area of skin that is swollen, red, or thick.

Write down your questions so you remember to ask them during your visits.
