摘要
目的探讨磁敏感加权成像(SWI)在检出脑微出血灶(CMB)及隐匿性CMB(rCMB)中的价值。方法回顾性分析45例有脑CMB患者的MR影像资料,观察病灶大小、部位等特征,比较常规MR成像序列及SWI序列的检出率。检查序列包括常规MR成像序列(T1WI、T2WI、FLAIR及DWI)及SWI序列。SWI采用Ven-Bold-HR三维梯度回波序列。结果共检出197个CMB,常规MR序列检出162个,SWI检出191个,SWI的CMB检出率是常规序列的1.18倍,两者的差异有统计学意义(χ2=22.90,P<0.01)。SWI序列可以检出常规序列不能检出的隐匿性CMB(rCMB)。结论 SWI在检出CMB及rCMB中优于常规MRI序列,建议作为MRI检查的常规序列之一。
