## Abstract A major difference between arterialβspinβlabeling MRI and goldβstandard radiotracer blood flow methods is that the compartment localization of the labeled spins in the arterialβspinβlabeling image is often ambiguous, which may affect the quantification of cerebral blood flow. In this st

## Abstract ## Purpose To investigate the feasibility and utility of arterial spin labeling (ASL) perfusion MRI for characterizing alterations of cerebral blood flow (CBF) in pediatric patients with arterial ischemic stroke (AIS). ## Materials and Methods Ten children with AIS were studied withi
## Abstract Partial volume effects (PVE) are a consequence of limited spatial resolution in brain imaging. In arterial spin labeling (ASL) MRI, the problem is exacerbated by the nonlinear dependency of the ASL signal on magnetization contributions from each tissue within an imaged voxel. We have de
