摘要
目的 探讨不同类型的急性缺血性脑血管病合并脑微出血（cerebral microbleeds,CMB）的阳性检出率及其临床意义.方法 将急性缺血性脑血管病患者204例以及同期健康体检者35例均行常规磁共振成像（magnetic resonance imaging,MRI）和磁共振梯度回波T2加权成像（T2＊-weighted gradient-echo magnetic resonance imaging,GRE-T2＊WI） 检查.结果 动脉粥样硬化血栓性脑梗死组、心源性脑栓塞组及腔隙性脑梗死组患者CMB阳性检出率均高于正常对照组,差异有统计学意义（P＜0.05）;短暂性缺血发作组与正常对照组的阳性检出率差异无统计学意义（P＞0.05）.结论 GRE-T2＊WI对CMB敏感性较高,对急性缺血性脑血管病患者的治疗和预后具有指导意义.
Objective To investigate the positive detection rate and clinical significance of different types of acute ischemic cerebrovascular disease combined with cerebral microbleeds （CMB）. Methods A total of 204 patients with acute ischemic c＇erebrovascular disease and 35 healthy control underwent examinations of magnetic resonance imaging （ MRI ） and T2 ＊ - weighted gradient - echo magnetic resonance imaging （GRE - T2 ＊ WI ）. Results The CMB positive detection rate of the atherosclerosis thrombosis cerebral infarction group, the cardiogenic cerebral embolism group and the lacunar cerebral infarction group were higher than the control group, and there were statistical differences between these groups （P 〈 0.05 ）. There was no significant difference between transient ischemic group （TIA） and control group in deteetion rate （P 〉 0.05 ）. Conclusion GRE - T2 ＊ WI has higher sensitivity to CMB, and it has a guiding role in the the therapy and the prognosis of patients with acute ischemie cerebrovascular disease.
