A new technique was presented for non-contrast volumetric time-resolved MRA (Contrast inherent INflow Enhanced Multi phase Angiography using pseudo-continuous arterial spin labeling; CINEMA-PCASL) . This technique requires no catheter insertion or contrast agent and provides useful qualitative information on the morphologic and dynamic filling of intracranial vessels. The feasibility study of CINEMA-PCASL sequence has been reported recently on healthy volunteers, but its clinical application in patients with AVMs has not been conducted. The purpose of this study was to evaluate the diagnostic use of non-contrast time-resolved MRA with time-of-arrival map in patients with cerebral AVM.
