Combined with cerebral blood flow (CBF) and bolus
arrival time maps, flow territory mapping delivers a
profound insight into the patients hemodynamics. In
this study, time encoded pCASL is extended with vessel
encoding gradients to acquire CBF, bolus arrival time
and flow territory maps with a single scan. Results are
compared to those of dedicated CBF and flow territory
pCASL scans, demonstrating that the post labeling delay
in standard pCASL, which is normally idle time, can be
utilized to generate both vascular territory and bolus
arrival time maps without adversely affecting CBF
quantification.
