摘要：

目的比较PROPELLER FSE和EPI两种扩散加权威像序列,探讨PROPELLER技术在诊断超急性脑梗塞中的应用价值。方法选取67例临床疑诊急性脑梗塞的患者分别行常规TIWI,T2WI,T2WI FLAIR序列检查和PROPELLER FSE扩散加权成像、EPI扩散加权成像,比较两种不同的弥散加权成像序列的图像质量,病灶检出率和对病变的显示程度。结果两个序列均可分辩出所有非颅底区域梗塞灶,对12个颅底病灶PROPELLER FSE DWI序列检出率达100%,而EPI DWI序列可检出率达58.3%。结论PROPELLER FSE扩散加权成像能提高图像信噪比,并有效消除颅底磁化率伪影,改善图像质量,提高颅底病变的检出率。
