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.
