CBF quantification in territorial arterial spin labeling (tASL) is difficult in practice due to unknown labeling efficiency as compared to non-selective ASL perfusion. It is also difficult to derive this labeling efficiency based on perfusion map due to the irregular cerebral region and potential multi-vessel supply. In this work, tASL MRA is used as a reference scan to derive the needed labeling efficiency for correct derivation of the CBF quantification.
