Abstract

Peripheral vascular disease has been evaluated using conventional imaging techniques such as contrast angiography to demonstrate the morphology and duplex sonography to evaluate the hemodynamic significance of a stenosis. Two-dimensional time-of-flight (TOF) magnetic resonance angiography (MRA) provides useful anatomic information in both normal and diseased popliteal and tibioperoneal vascular segments, whereas corresponding velocity-encoded cine MR determined velocities and waveforms correlate well with those determined using color-coded sonography and showed excellent interstudy reproducibility. Velocity-encoded cine MR may be useful in assessing the hemodynamic significance of a peripheral vascular stenosis whose severity might be overestimated by using MRA alone. When two-dimensional TOF MRA is combined in a complementary manner with velocity-encoded cine MR, the anatomic information from contrast angiography and the physiologic information from duplex sonography can be obtained during the course of one MR examination.
