Amide proton transfer weighted (APTw) MR imaging enables detections of metabolite and pH value changes, while the arterial spin label (ASL) imaging can assess hemodynamic changes in brain tissue after cerebral infarction. This study aimed to evaluate correlation between APT-related metabolic changes and blood flow status in the infarct core of patients with subacute ischemic stroke by APTw and ASL MR techniques. Significant correlations of APT to apparent diffusion coefficient (ADC) and cerebral blood flow (CBF) values in the infarct region were observed.
