Knowledge
of blood transit time in major blood vessels can provide important clinical information
about vascular circulation. It can also facilitate the selection of labeling
delay in ASL for quantification of CBF. Here a novel method of measuring
blood transit time is proposed, which used slice-selective spin labeling
followed by multiple delay time points with very short interval. Transit time
estimation in different blood circulation segments was demonstrated.
