MR Angiography (MRA) MR angiography (MRA) uses a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities or diagnose atherosclerotic (plaque) disease.
What vessels and diseases do neuroradiologists study with MRA? MRA can be used to evaluate most major arteries in the body. Neuroradiologists use MRA to examine the carotid arteries in the neck and the cerebral vessels in the brain. MRA can show their shape, size, location, and orientation. With this information, neuroradiologists can diagnose diseases in these vessels and then determine the best way to treat them.
