MRA vs MRI Scans
Much like MRI scans, an MRA scan is a type of magnetic resonance imaging procedure used to diagnose conditions in the body. A magnetic resonance angiogram (MRA) produces more detailed images, compared to an MRI, of blood vessels and blood flow throughout the body.
Why Might You Need an MRA Scan?
There are several reasons why your doctor may recommend an MRA test. Usually, an MRA scan will be accompanied by an MRI. The purpose of an MRA brain scan is to assess any abnormalities with blood supply to the brain. If your doctor believes you have a narrowing or blockage of blood flow, they may suggest you get an MRA. Symptoms of blocked or narrowed blood flow may include fatigue, dizziness, festinating gait, and forgetfulness, amongst other indications. Conditions an MRA can detect include:
- The causes of a stroke
- Signs of heart disease
- Aneurysm: dilatation of an artery wall
- Aortic coarctation: congenital disorder affecting blood flow to the heart
- Aortic dissection: a tear in the inner layer of the main aorta
- Renal artery stenosis: a condition that narrows the arteries which carry blood to the kidneys
What To Expect During Your MRA Scan
During an MRA scan, you will be asked to lie very still inside of an MRA machine, which is similar to an MRI machine. The MRA scanner will obtain detailed images of your blood vessels to detect any of the aforementioned conditions. You will be asked to remove any metal jewelry from your person so it does not interfere with the scan. This procedure is noninvasive and will help your radiologist diagnose any condition which may be affecting the blood flow throughout your body.
