Association of Pretreatment Perfusion Imaging Parameters with 90-Day Excellent Functional Outcomes in Anterior Circulation Distal Medium Vessel Occlusion Stroke [CLINICAL]

BACKGROUND AND PURPOSE:
Acute ischemic strokes caused by distal medium vessel occlusions (DMVOs) represent a remarkable proportion of all stroke cases, yet the predictors of excellent functional outcomes in these patients remain poorly understood. This study aims to identify pretreatment CTP parameters associated with excellent functional outcomes, defined as an mRS score of 0–1 at 90 days, in patients with anterior circulation DMVO.

MATERIALS AND METHODS:
We conducted a retrospective mul…
