Magnetic Resonance Angiogram of Circle of Willis

MRA stands for “magnetic resonance angiography”. In short, MRA of the head is a relatively quick (20 minutes), extremely accurate noninvasive test to get a close look at the arteries in your head. It is extremely good at finding narrowed arteries (stenosis), brain aneurysms, fistulas, and arterovenous malformations. (adapted from sikermedical link)
