In the present study, we demonstrated the clinical utility of acceleration-selective arterial spin labeling (AccASL) MR angiography (MRA) in brain arteriovenous malformations (AVMs). AccASL-MRA significantly improved the visualization of AVM in comparison with time-of-flight (TOF)-MRA. AccASL-MRA could detect the nidus and draining veins in all patients. In particular, the detection of deep venous drainage by AccASL-MRA led to the accurate Spetzler-Martin grading. AccASL-MRA could serve as a noninvasive tool to evaluate brain AVMs without the use of contrast agents.
