What is an MRA?
Magnetic Resonance Angiography, or MRA, is extremely helpful in pinpointing blockages and other abnormalities that may exist in blood vessels.
What can you expect?
When you arrive at Renaissance Radiology, the receptionist will help you with your paperwork and show you where to leave your personal belongings during the exam.

When it’s time for your MRA, the technologist will ask you to simply lie down on a cushioned table, which will automatically move into the magnet after you have been comfortably
positioned for scanning.
The technologist will leave the magnet room, but you will be in constant contact with him or her throughout the entire exam.
When the exam begins, you will hear a muffled thumping sound, which will last for several minutes. Just relax and try to lie as still as possible, since any movement will distort and blur the images. You can even listen to your favorite CD while your scan is being performed.
With the exception of cerebral and intracranial MRA, during your MRA, you may be injected with contrast. The agent used is safe and does not contain iodine, and the injection is painless. Once the exam is complete, the technologist will assist you off the table.
How long will the exam take?
Your entire exam will take from 30 to 90 minutes, depending on the type of study your doctor has ordered.
How do you prepare for your MRA?
No special preparation is necessary for most MRA exams. Metallic objects, or items containing metal, often compromise the image quality, so please do not wear: |
To ensure that you are able to lie quietly and still during your MRA, you may want to avoid drinking coffee or other caffeinated beverages prior to your exam. If you are having an MRA of the renal artery, please do not eat four hours prior to your exam.
Are there any restrictions?
Metallic items within the body may cause some people to be excluded from having an MRA. On the day of your exam, make sure the staff at Renaissance Radiology knows if you have: |
|
A pacemaker |
|
A metal plate |
|
pin or other metallic implant |
|
Aneurysm clips |
|
An artificial heart valve |
|
An intrauterine device (IUD) |
Also, be sure to let the staff know if you are pregnant or if you have ever been a metal worker or been wounded during military service.
When will you know the results?
Once your MRA exam is complete, a board-certified radiologist at Renaissance Radiology will look at the images. The radiologist will interpret the scans and will send your doctor a written report within 24 to 48 hours.
If you have any additional questions, please talk to your doctor.
