分水岭梗死指两条主要动脉供血区边缘带之间的局限性梗死,分为两类:一是位于大脑中动脉与大脑前动脉或大脑后动脉的皮层支之间的梗死灶,称作称皮层分水岭梗死。二是大脑中动脉的深穿支及表浅穿支之间或大脑中动脉及大脑前动脉的表浅分支之间边缘带的梗死灶,称作皮层下分水岭梗死(IWI)。本研究应用弥散磁共振成像(DWI)来确定颈动脉系统的急性 IWI 病灶,并探讨其与相关血管病变及
Watershed infarction refers to the localized infarction between the marginal zones of the two main arterial blood supply areas and is divided into two categories: one is the infarction between the middle cerebral artery and the cortical branch of the anterior cerebral artery or posterior cerebral artery called the cortex Watershed infarction. The other is the infarct zone at the marginal zone between the deep and middle superficial branches of the middle cerebral artery or between the superficial branches of the middle cerebral artery and the anterior cerebral artery called subcortical watershed infarction (IWI). In this study, diffuse magnetic resonance imaging (DWI) was used to determine the acute IWI lesions of the carotid system and to explore its relationship with related vascular lesions and
