Magnetic Resonance Angiography (MRA)

What is an MRA?

Magnetic Resonance Angiography is an exam that uses a strong magnetic field and radio waves to study the body’s anatomy and blood vessels.

MRA Prep:

No dietary prep unless you are having an MRCP. An MRCP is a study of the biliary ducts. You will need to not eat 12 hours prior to your exam.

MRA Procedure:

For this test you will be taken out onto a mobile unit truck. You will need to pre-certify your exam with your insurance company. When your MRA is scheduled, you will be given a 1-800-559-7226 phone number to pre-register. They will be asking several questions pertaining to metal since you will be scanned by a magnet. You may be required to have x-rays of your eyes, if you work around metal.

Please review the following list. If any item applies to you, please inform the scheduling department.

  • Surgical staples
  • Metal implants
  • Ear Prosthesis (implants)
  • History of foreign body in eyes
  • Aneurysm clips
  • Dental Bridges
  • Pacemaker
  • Shrapnel (bullets)
  • Hearing aids
  • Pregnancy
  • Inferior Vena Cava Filters

If you are claustrophobic, you may want to ask your physician for medication to help you relax.

Patient Preparation Instructions:

  1. Follow your normal routine, eat normally, and take any medication you regularly take.
  2. Wear clothing with the least amount of metal as possible.
  3. No metal hairpins or barrettes.
