Pseudo-continuous arterial spin-labeled (pCASL) carotid MR angiography provides excellent arterial-to background contrast but may produce artifacts in patients who move or swallow during the exam. The aim of this work was to describe a self-configuring and hybrid pseudo-continuous and pulsed spin labeling preparation that incorporates background suppression to reduce motion-related artifacts as well as improve vascular contrast-to-noise ratio in pCASL-based carotid MRA.
