We present a novel approach with parallel excitation for spatially selective pseudo CASL to perform vessel selective arterial spin labeling (ASL). Previously, several methods have been proposed to perform vessel selective ASL, but they are either vulnerable to motion due to acquiring multiple images or limited in selectivity. We use multiple RF transmission coils to tag only the desired vessel and to leave the other vessels untagged. Our approach provides superior spatial selectivity and high inversion efficiency, making it an efficient tool for vessel selective ASL.
