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.
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 kidneys is done to look at the blood vessels leading to the kidneys. It checks for narrowing (stenosis) and blockage of the blood vessels. The test helps the doctor find vessels that need treatment and plan the treatment. For example, a "road map" of blood vessels to the kidneys can help the doctor during surgery for kidney cancer or help the doctor choose which kidney would be best to take for a kidney transplant.
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.
