Evaluating cerebrovascular reactivity measured by velocity selective inversion arterial spin labeling with different post‐labeling delays: The effect of fast flow

Feng Xu, Cuimei Xu, Dan Zhu, Dapeng Liu, more

Magnetic Resonance in Medicine > 92 > 5 > 2065 - 2073

Purpose Velocity selective arterial spin labeling (VSASL) quantification assumes that the labeled bolus continuously moves into the imaging voxel during the post‐labeling delay (PLD). Faster blood flow could lead to a bolus duration shorter than the applied PLD of VSASL and cause underestimation of cerebral blood flow (CBF). This study aims to evaluate the performance of velocity‐selective inversion...
