The multiple time points territorial arterial spin
labelling (tASL) was conducted in healthy volunteers and
patients with cerebrovascular occlusive disease. We
propose an accumulated-area map, accumulating the
perfusion pixels picked up by t-test, of all phases in
each vessel territory. We also calculate the Percentage
Perfusion-Territory Area (%PT-A) from the
accumulated-area map. We discuss the validity and
clinical usefulness of this unique approach to the tASL.
