Abstract
Magnetic resonance angiography is a promising new technique for vascular imaging. MRA is based on gradient recalled acquisitions to maximize flow-related enhancement. The two major methods of MRA are time-of-flight and phase contrast. This article examines the time-of-flight method, and also includes a discussion of hemodynamics and the effects of scanning parameters.
