Abstract:
Objective To explore the differential diagnosis of middle cerebral artery(MCA)embolic infarction and perforating artery infarction based on 3.0T vessel wall magnetic resonance imaging(VW-MRI)characteristics of the head and neck.Methods The data of 148 patients with MCA infarction were retrospectively analyzed.According to the infarction sites,all patients were divided into non-perforating artery infarction group(n=77)and perforating artery infarction group(n=71).All patients underwent routine MRI and VW-MRI scans.MCA stenosis rate,stenosis degree,remodeling index(RI),remodeling mode and plaque properties were evalu-ated,respectively.Results There was no significant difference in stenosis rate,stenosis degree,RI and remodeling mode between the two groups(P＞0.05),but there were significant differences in incidence of intraplaque hemorrhage and irregular plaques,plaque site and enhancement degree between the two groups(P＜0.05).Conclusion The differences in VW-MRI characteristics of different types of MCA infarction are mainly reflected in plaque properties,which provide useful information for clinical determina-tion of infarction types.
