Conventional arterial transit delay measurements consist of a series of separate ASL experiments acquired at several different post-labeling delays. Such measurements are usually time-consuming and can be formidable overheads for ASL studies. The time requirement also makes the measurements highly sensitive to motion. This study presents a simple yet effective modification of the conventional method for measuring transit delay with shorter scan time and less motion sensitivity. Such a method could be beneficial to all ASL studies.
