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.
