Scatterplot showing the relationship between cerebral blood flow asymmetry index (CBF-AI) and cerebral vascular reserve (CVR). Vertical dashed line: CBF-AI threshold (< 0.8); horizontal dashed line: CVR < 10%. These threshold values were adopted based on previously published studies1,4,5,8 indicating their association with cerebral hemodynamic impairment and hyperperfusion risk, and were not newly defined in this study.
