This abstract introduces estimating arterial transit time (ATT) with spatial specificity by using vessel selective ASL (veASL). Both conventional ASL and veASL were performed for comparison of the derived ATT map. Experiments showed that transit time derived from veASL was longer, suggesting the interested region is likely being fed by both ICAs and VAs with blood in ICAs arrived earlier. In this abstract, ATT estimation with blood supply specificity was introduced. It's helpful for choosing optimal PLD in veASL and studying hemodynamic properties of artery.
