In this study, the main purpose was to explore the feasibility of 3D pseudo-continuous territory arterial spin labeling (tASL) in evaluating unilateral middle cerebral artery (MCA) recanalization. We included 47 patients with unilateral MCA stenosis diagnosed by DSA and performed tASL examination. Increased relative cerebral blood flow (rCBF) values were found in the blood supply area of MCA postoperatively than pre-operatively. Good prognosis was also revealed to closely associate with Alberta Stroke Program Early CT Score (ASPECTS) scores based on tASL perfusion images. Therefore, tASL can be used as one valuable method to diagnose the effect of vascular recanalization.
