MRA of the Brain: Exam Description

Your doctor has ordered a MRA (Magnetic Resonance Angiography) of your brain. MRA uses a magnetic field, radio waves and a computer to create images of soft tissues, bones, and internal body structures. An MRA of the brain is used to produce two three-dimensional images of the blood vessels. MRA is primarily used to detect narrowing of the arteries and to rule out aneurysms.

HOW DO I GET READY FOR MY EXAM?

We recommend you print and fill out the MRA questionnaire form before arriving. It will help accelerate your registration process.

If you are claustrophobic (fear of enclosed spaces) or experience intense pain while lying down for more than 10 minutes, we recommend you contact your referring physician and request a relaxant or pain medication to help you through the scan. The radiology physicians will not prescribe these medications for you.

WHAT SHOULD I DO AFTER ARRIVING FOR MY EXAM?

  • Please check-in at the main registration desk and then check-in at the radiology reception desk.
  • Please inform the technologist(s) if you have any allergies, are pregnant or are nursing or if you have an aneurysm clip(s), pacemaker, bone growth stimulator, pain pump, and/or other electronic implanted device(s).

WHAT SHOULD I EXPECT DURING MY EXAM?

  • The MRA of the brain requires you to lie down on the scanning table, head-first.
  • A coil (special device) will be placed around your head to obtain the best image quality possible. 
  • The scanning table will slide your body into the magnet.
  • During the scan, you will not feel anything, but will hear intermittent humming, clicking and knocking sounds. Earplugs will be required during the scan to help mask the noise.
  • It is very important to remain very still during the scan to obtain the optimal image quality.
  • The technologists will be able to see and hear you at all times during the exam. You will also be provided an emergency device to obtain the technologist's attention at any time, if needed.
  • The MRA of the brain will take approximately 15 minutes.

WHAT DO I DO AFTER MY SCAN?

  • The images of your scan will be examined by a radiologist and the results will be sent to your referring physician who will review the results with you.
  • You can request copies of your images on a CD-ROM or your report, by calling (805) 692-6435.
