Magnetic Resonance Angiogram (MRA)
A magnetic resonance angiogram (MRA) is a type of Reference magnetic resonance imaging (MRI) Opens New Window scan that uses a magnetic field and pulses of radio wave energy to provide pictures of blood vessels inside the body. The Reference radiologist Opens New Window may talk to you about the results of your MRA right after the test. Complete results are usually available for your doctor in 1 to 2 days.
The blood vessels look normal and the blood flow through them is not reduced or stopped. No blood clots or large Reference plaque Opens New Window buildup is seen.
Blood vessel walls are normal. No bleeding, abnormal collections of fluid, blockage in the flow of blood, or bulges in the blood vessels (Reference aneurysms Opens New Window) are present.
Partial or complete blockage of a blood vessel may be seen. Blockage may be caused by a blood clot, the buildup of fat and calcium deposits (plaque), or narrowing (stenosis) of the blood vessel.
A bulge (aneurysm) in the blood vessel wall may be seen. Damage to the wall of a blood vessel may be seen.
Conventional angiogram or a Reference CT angiogram Opens New Window (computed tomography angiogram) may be needed after MRA if a problem, such as an aneurysm, is found or if surgery may be needed.
