摘　　要：目的探究三维高分辨磁共振管壁成像(3D-HR-VWI)技术对于穿支动脉所致缺血性卒中的应用价值。方法回顾性纳入2016-2018年38例缺血性卒中患者,使用3D-HR-VWI技术,显示患侧和健侧豆纹动脉结构,以研究穿支动脉病变特点。结果病变侧与正常侧的豆纹动脉绝对数量无显著统计学差异(P=0.251 2),豆纹动脉数量比在2组中的分布有显著统计学差异(P=0.020),病变侧豆纹动脉显示深度在组间同样有统计学差异(P=0.032),危险因素包括高血压、糖尿病、高血脂及吸烟组间未见显著统计学差异,外侧豆纹动脉组、内侧豆纹动脉组及内+外侧豆纹动脉组中,血管受累、M1段病变长度、病因学分型、豆纹动脉数量及豆纹动脉深度特征均无显著统计学差异。结论 3D-HR-VWI技术能够清晰显示豆纹动脉及穿支动脉病变情况,对于判断穿支动脉病变导致的缺血性卒中有一定的诊断价值。Objective To study the value of three-dimensional high-resolution magnetic resonance wall imaging (3D-HR-VWI) for ischemic stroke caused by perforating artery infarction.Methods Retrospectively studied 38 patients between 2016 and 2018.3D-HR-VWI technique were used to examine the structures of the ipsilateral and contralateral lenticulostriate arteries of the lesion, to study the characteristics of the perforating artery lesion.Results There was no statistical significance in the absolute number of lenticulostriate arteries on the lesion side and the normal side (P=0.2512). There was statistical significance in the ratio of lenticulostriate arteries between two groups (P=0.020). The differences of the depth of lenticulostriate arteries on lesion sides were also statistical significant between two groups (P=0.032). The differences among risk factors including hypertension .diabetes, hyperlipidemia and smoking were not statistically significant.There was no statistical significance on the differences of vascular involvement,length of M1 lesions,etiological types, number of lenticulostriate arteries,and depth of lenticulostriate arteries among the lateral lenticulostriate artery group, the internal lenticulostriate artery group and the interna1+lateral lenticulostriate artery group.Conclusion 3D-HR-VWI can show the lesions of lenticulostriate arteries and perforating arteries,which is of important in diagnosis of perforating artery infarction.
