脑微出血是一种亚临床的终末期微小血管病变导致的含铁血黄素沉积,广泛存在于脑血管疾病、阿尔茨海默病、血管认知障碍患者以及正常老年人群中~([1])。MRI对于脑部疾病的诊断具有重大意义,而当前的研究对于前、后循环脑梗死患者脑微出血灶分布特点及其高危因素的阐述,仍不是很清楚。磁敏感加权成像(SWI)采用高分辨率三维扰相梯度回波(GRE)序列可较常规MRI
Cerebral microaemorrhage is a subclinical end-stage microvascular disease caused by hemosiderin deposition, widespread in cerebrovascular disease, Alzheimer’s disease, vascular cognitive impairment and normal elderly population ~ ([1] ). MRI for the diagnosis of brain disease is of great significance, and current research on the distribution of cerebral micro-hemorrhage in patients with cerebral infarction before and after the characteristics and risk factors elaborated, it is still not clear. Magnetic resonance weighted imaging (SWI) using high-resolution three-dimensional spoiler gradient echo (GRE) sequence can be more conventional MRI
