| 摘 要： | 目的 探讨磁敏感加权成像技术(SWAN)在腔隙性脑梗死中的临床应用价值.方法 采用美国通用电器SIGNAEXCITE 3.0T磁共振成像系统,应用SWAN和其他常规技术(包括GRE序列T1和T2、T2梯度回波、T2FLAIR、DWI).对42例腔隙性脑梗死患者进行对比研究,其中18例合并高血压病,4例合并2型糖尿病,12例合并有高血压病及2型糖尿病,应用3.0T磁共振成像系统行常规MRI和SWAN序列成像检查,并结合临床资料进行分析.结果 23例腔隙性脑梗死患者脑内有微出血灶,在SWAN上呈点状、圆形、椭圆形低信号.总数达123个,分布于皮层、皮层下、基底节区、丘脑,脑干和小脑.结果 显示其他序列检测出大多数腔隙性脑梗死病灶比SWAN敏感;但相比于GRE序列,SWAN能更好地显示脑微出血(CMBs)、微小血管和细小的血管畸形以及其他小血管性病变,SWAN显示腔隙性脑梗死并发CMBs明显优于常规序列.结论 磁共振SWAN技术可以更好地显示腔隙性脑梗死并发的CMBs及梗死区域小静脉情况,确定腔隙性脑梗死是否合并CMBs对于其治疗方案的确定起着重要的作用,同时通过对腔隙性脑梗死患者进行SWAN检查,发现CMBs的发生率较高,且与腔隙性脑梗死的数目相关,提示CMBs与腔隙性脑梗死同属脑内微小血管病损的标志.
