What is an MRA?

MRA (Magnetic Resonance Angiography) is a specialized type of MRI exam used to obtain images of the arteries of the brain, carotid arteries, aorta, renal arteries and vessels of the extremities. MRA is used to detect problems with blood vessels that may be causing reduced blood flow. 

Where can I schedule this exam?

An MRA (Magnetic Resonance Angiography) exam can be scheduled at:

How should I prepare for my exam?
  • Nothing to eat 2-4 hours prior to your exam (specific instructions will be given prior to your exam).
  • Since MRI uses a magnetic field to obtain images, it is necessary to take precautions. Please review the MRI metal-safety checklist.
  • Wear comfortable clothes without metal fasteners, including zippers, buttons and snaps. Depending on the particular exam, you may be asked to change into scrub-type clothing that we will provide.
  • Please let us know if you have an insulin pump or glucose monitor. Our imaging machines may cause your device to malfunction, so it will need to be removed during your exam.
How long will my exam take?

An MRA exam will take about 30 minutes.

What happens during my exam?

Your exam may require contrast material to be injected through an IV. In this case, an IV will be placed in your arm before the scan starts. You will be positioned on a cushioned table inside the MRI scanner. The scanner will make a drumming sound as it captures the images. You may listen to music to muffle this sound if you’d like. To ensure the best quality images, you will be asked to remain as still as possible during the exam.

What happens after my exam?

Your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.

You may resume regular activities immediately after your exam.
