MRA evaluation of AVMs requires both high spatial resolution and high temporal resolution, which has been made possible by recently developed accelerated imaging techniques. The purpose of this work was to describe the application of one such technique, CAPR, to imaging of AVMs of the upper and lower extremities. Six patient studies have been performed, successfully imaging AVMs of the forearm, hand, thigh and foot. CAPR CE-MRA shows diagnostic quality time-resolved imaging of AVMs of the upper and lower extremities, which may be useful for assessment of the AVM as well as planning of sclerotherapy.
