In recent years, time-resolved 4D-MRA technique based on arterial spin labeling (ASL) methods has been widely reported. In addition, vessel selective 4D-MRA (VS 4D-MRA) can be obtained using spatial free labeling slab based on pulsed ASL technique. The aim of this study was to assess the usefulness of VS 4D-MRA for the assessment of feeding artery in intracranial AVM. This study revealed that additional information of feeding arterial flow was obtained using VS 4D-MRA compared to conventional TOF-MRA. This technique can be useful for the evaluation of intracranial AVM as additional information.
