How does arterial spin labeling (ASL) perfusion imaging improve interpretation of BOLD‑based fMRI endpoints in drug studies?

Arterial spin labeling (ASL) supplies quantified cerebral blood flow (CBF) maps that help resolve key ambiguities inherent in BOLD fMRI signals, improving attribution of drug effects to perfusion vers...
