This study used 3D pseudo-continuous arterial spin labeling (pcASL) to compare cerebral blood flow (CBF) patterns in minimally conscious state (MCS) patients with those in vegetative state (VS) ones. The results identified different CBF patterns within specific brain regions in VS patients compared with MCS. ASL may serve as an adjunctive method to separate MCS from VS in DOC patients, and could be used in longitudinal assessments of patients with severe brain injuries.
