Pseudo-continuous arterial spin labeling (PCASL) has been reported to provide better signal to noise ratio than pulsed arterial spin labeling for carotid MR angiography. The purpose of this study was to determine the accuracy of PCASL MRA for quantifying carotid artery stenosis (CAS) in patients with sonographically documented CAS. Accuracy was assessed relative to conventional 3D TOF and contrast-enhanced MRA techniques.
