Investigating white matter perfusion using optimal sampling strategy arterial spin labeling at 7 Tesla

Cerebral blood flow (CBF) is an informative physiological marker for tissue health. Arterial spin labeling (ASL) is a noninvasive MRI method of measuring this parameter, but it has proven difficult to measure white matter (WM) CBF due to low intrinsic contrast‐to‐noise ratio compared with gray matter (GM). Here we combine ultra‐high field and optimal sampling strategy (OSS) ASL to investigate WM CBF in reasonable scan times.
