What is an MRA (MR Angiography)?
Angiography is a medical test that allows physicians to diagnose and treat medical diseases and conditions that affect the blood vessels. These exams generate images of major blood vessels throughout the body and can be done with three different imaging technologies including fluoroscopy, computed technology (CT) and magnetic resonance imaging (MRI).
How does an MRA work?
MR angiography (MRA) utilizes a powerful magnetic field, radio waves and a computer to analyze blood vessels and diagnose abnormalities or plaque disease. Ionizing radiation is not used and may need a contrast injection known as gadolinium, which has a less likely chance of causing allergic reactions than iodinated contrast material.
When is an MRA recommended?
In general, your health care provider will order this exam if they suspect there is a bloodline blockage or narrowing of blood vessels in the body. In addition, below are a few other conditions that your provider may want to observe:
- Determine underlying cause of stroke
- Signals of heart disease
- A narrowing of the aorta, or aortic coarctation
- Narrowing or blockage of the vessels in the arms or legs
How do I prepare for an MRA scan?
Dress apparel will not matter as once you arrive for your exam you will be asked to change into a gown and remove all jewelry and piercings.
In general, you can eat/drink as usual, but it is advised not too, if possible, just so you can avoid any necessary bathroom trips during your MRA scan.
Before the exam you will be asked to answer a few questions to ensure safety during this procedure. Some important questions can be if you have reason to believe you are pregnant or if you have metals within your body. It’s crucial to answer these questions as accurate as possible and to the best of your knowledge.

What to expect after an MRA exam?
Once the MRA scan is complete, the technician will come back into the room and slide you out of the machine. They will remove the IV if you were given it prior to the exam. You will be taken to another room to get dressed back into regular clothing and should be able to go on your way. Results of the exam will be sent to your doctor, and they will reach back out once they have carefully observed the results.
