An automatic scoring system for assessing reperfusion status based on arterial spin labeled (ASL) perfusion MRI was developed and evaluated for acute ischemic stroke patients who received thrombolysis and/or endovascular treatment. Reperfusion injury is considered to have the same detrimental effects as non-reperfusion, and we applied the ASPECTS model to address the existence of heterogeneity of hypo- and hyper-perfusion despite vessel recanalization. Our newly devised reperfusion scoring system is highly associated with patient functional outcome and provides a useful tool to complement other clinical methods for managing corresponding strategies after treatment.
