摘要 目的:探讨MRI联合弥散加权成像(DWI)对腹膜转移癌的诊断价值。方法:35例可疑腹膜转移癌患者均行MRI联合DWI扫描,由两名经验丰富的影像医生在不知手术病理及临床随访结果的情况下对图像分部位进行分析,采用受试者工作特征曲线(receive operating characteristic curve,ROC曲线)分析扫描结果 ,判断患者是否为腹膜转移癌并总结其MRI表现及常见部位。结果:MRI联合DWI诊断方法的曲线下面积AUC、灵敏度和特异度分别为0.833,85%和73.5%。MRI诊断方法则分别为0.683,72.1%和66.7%,两组AUC结果有统计学差异(P<0.05)。结论:MRI联合DWI可明显提高腹膜转移癌的检出率。
