Acceleration of cerebral blood flow and arterial transit time maps estimation from multiple post-labeling delay arterial spin-labeled MRI via deep learning. (arXiv:2206.06372v1 [eess.IV])

Purpose: Arterial spin labeling (ASL) perfusion imaging indicates direct and
absolute measurement of cerebral blood flow (CBF). Arterial transit time (ATT)
is a related physiological parameter reflecting the duration for the labeled
spins to reach the brain region of interest. Multiple post-labeling delay
(PLDs) can provide robust measures of both CBF and ATT, allowing for
optimization of regional CBF modeling based on ATT. The prolonged acquisition
time can potentially reduce the quality and accuracy of the CBF and ATT
estimation. …
