Abstract：Objective To study the application of high resolution vessel wall imaging(HR-VWI)in patients with craniocere-bral arteriosclerosis and the plaque characteristics.Methods In this study,120 patients with suspected craniocerebral arterio-sclerosis admitted to our hospital were selected.All patients were scanned by multi-slice spiral CT(MSCT)and high resolution vessel wall imaging(HR-VWI)technology.We compred the detection rate of vascular plaques in patients with cerebral arterio-sclerosis by two scanning techiques,and then,compared the differences between mild,moderate and severe patients.Then,the patients with MR finding were reclassified as symptomatic group and asymptomatic group.By means of MR software processing system,the quantitative indicators of blood vessels and plaques were compared between two groups of patients,in terms of steno-sis rate,plaque load,remodeling index(RI),and macular stability.Results Compared with MSCT,HR-VWI could accu-rately detect the plaque area,vascular remodeling rate,stenosis rate,plaque load and enhancement index between symptomatic and asymptomatic patients,with statistical differences(P<0.05).HR-VWI had a higher detection rate of non-calcified plaque,and the difference was statistically significant(P<0.05).Conclusion HR-VWI has a high diagnostic efficiency for cerebral arteriosclerosis,which can accurately detect the plaque characteristics and accurately analyze plaque characteristics.
