Abstract
Magnet resonance angiography (MRA) is a nonin-vasive method which provides images similar to those obtained by digital subtraction angiography (DSA). Blood motion causes two phenomena that change longitudinal and transverse spin magnetization. First, time-of-flight (TOF) effects arise from the movement of longitudinal magnetization during a relatively long period. The second flow phenomenon occurs when transverse magnetization moves in the direction of a magnetic field gradient resulting in phase shifts. Both effects can be exploited to generate angiographic images (see also Chap. 1).
