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.
