ABSTRACT
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 201 6 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＝0.251 2).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 internal+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.
