Partial volume correction for arterial spin labeling using the inherent perfusion information of multiple measurements

Partial volume correction for arterial spin labeling using the inherent perfusion information of multiple measurements

Abstract Background Arterial spin labeling (ASL) provides a noninvasive way to measure cerebral blood flow (CBF). The CBF estimation from ASL is heavily contaminated by noise and the partial volume (PV) effect. The multiple measurements of perfusion signals in the ASL sequence are generally acquired...
