MR an·gi·og·ra·phy (MRA),

imaging of blood vessels using special magnetic resonance (MR) sequences that enhance the signal of flowing blood and suppress that from other tissues.

magnetic resonance angiography

A term for the magnetic resonance imaging of selected vascular structures—e.g., circle of Willis or the carotid arteries.

magnetic resonance angiography

Peripheral MR angiography Imaging An imaging technique in which a contrast dye is injected into a blood vessel and magnetic resonance is used to create an image of the flowing blood through the vessel; often used to detect stenosis of the cerebral arteries. See Contrast enhanced method–MRI, Phase contrast method–MRI, Time-of-flight method.
