摘要 脑梗死是脑部最常见的缺血性血管疾病,随着我国人口老龄化的加重,脑梗死的发病率近年程持续上升趋势,脑梗死的发病率已占到脑血管疾病的75%。急性脑梗死尤其在溶栓治疗后容易合并脑出血,及时诊断梗死后出血直接关系到患者的预后。脑微出血(cerebral microbleed,CMB)是以脑内微小量出血为特点,CMB的临床诊断一般采用CT、磁共振成像(MRI)。磁敏感加权成像(SWI)是一种新的三维采集成像信号的序列,对磁场均匀性改变的信号采集非常敏感。笔者对我院31例脑梗死患者的CT与SWI的影像学比较进行回顾性分析,从而找出最佳的影像学检查方法。31例,其中男性19例,女性12例,年龄36~88岁,平均(62±6)岁。患者纳入标准:急性脑梗死治疗后怀疑脑出血患者。患者排除标准:①生命体征不稳定不能配合MRI检查;②)幽闭恐惧症。
