MRA (magnetic resonance angiogram) is a type of magnetic resonance imaging (MRI) scan that uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body. A standard MRI cannot provide a good picture of the blood vessels and blood flow.
People who have an MRA also may have an MRI.
When you have an MRA, you lie on a table and the table moves into the MRI machine. An MRA is done with the same machine as an MRI.
An MRA of the head is done to look at the blood vessels leading to the brain to check for a bulge (aneurysm), a clot, or a narrowing (stenosis) because of plaque.
Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if you have any problems.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
