Effects of Arterial Transit Delay on Cerebral Blood Flow Quantification using Arterial Spin Labeling in an Elderly Cohort

摘要

PurposeThis study is to investigate whether measurement of arterial transit time (ATT) can improve the accuracy of Arterial Spin Labeling (ASL) cerebral blood flow (CBF) quantification in an elderly cohort due to the potentially prolonged ATT in the cohort.
