Intracranial MR angiography using acceleration-selective arterial spin labelling (AccASL) was implemented and images acquired in five healthy volunteers and the peripheral vessel visualization in the middle cerebral artery (MCA) area were compared with time-of-flight (TOF) approach. We show that AccASL can visualize peripheral arterial both selectively (without venous signal) and with better efficiency compared to the TOF approach.
