Abstract：Objective To evaluate the value of high-resolution magnetic resonance vessel wall ima-ging(HRMR-VWI)in assessment of the severity of vascular stenosis in elderly patients with acute cerebral infarction(ACI).Methods A total of 127 elderly ACI patients admitted to our department between May 2021 and January 2024 were retrospective enrolled,and according to the degree of vascular stenosis by digital subtraction angiography(DSA),they were divided into a normal group(31 cases),a mild group(40 cases),a moderate group(40 cases),and a severe group(16 cases).DSA and HRMR-VWI were performed to evaluate the plaque and severity of vascular stenosis.ROC curve was plotted to evaluate the diagnostic value of HRMR-VWI parame-ters for the degree of vascular stenosis in the elderly ACI patients,and the AUC values of these parameters were calculated.Results Significant differences were observed in the HRMR-VWI pa-rameters such as plaque area and plaque burden among the normal,mild,moderate and severe groups(P＜0.01).ROC curve analysis showed that the AUC value of the combined plaque area and plaque burden in diagnosis of mild,moderate and severe vascular stenosis in elderly ACI pa-tients was obviously higher than that of the two parameters alone(0.964 vs 0.822,0.843,P＜0.05;0.930 vs 0.795,0.776,P＜0.05;0.917 vs 0.786,0.792,P＜0.05).Conclusion HRMR-VWI can effectively evaluate vascular stenosis in elderly ACI patients,which providing important refer-ence for early treatment and prognosis improvement.
