【摘要】 目的　探讨CT腹膜腔造影 (computedtomographyperitoneography,CTP)对腹膜转移瘤的诊断价值及临床意义。方法　回顾性研究有完整病史资料及手术病理结果 ,并经CT平扫及CTP检查的腹膜转移瘤 2 5例 ,其中 2 0例CT平扫及CTP发现与手术结果进行了对照。结果　CT平扫及CTP在所有腹膜受累部位对腹膜转移瘤的敏感性分别为 47 5 %和 76 8% (χ2 =16 92 ,P <0 0 0 5 ) ,尤其在双侧膈下间隙及结肠旁沟CTP的敏感性较高 ,分别为 88 0 %和 74 0 %。结论　CTP是诊断腹膜转移瘤有效的影像学方法 ,CTP诊断腹膜转移瘤优于CT平扫更多还原

【Abstract】 Objective To investigate the diagnostic value and clinical significance of computed tomographic peritoneography(CTP) for peritoneal metastases Methods Twenty five cases with peritoneal metastases examined by plain CT and CTP with complete clinical informations and surgical pathologic results were retrospectively analyzed and correlative study was done in 20 cases Results The sensitivity of plain CT and CTP for detection of peritoneal metastases at all sites of involvement was 47 5% and 76 8%,respectively (χ 2=16 92, P <0 005) For CTP, the highest sensitivity was in the bilateral subphrenic spaces (88 0%) and paracolic gutter(74 0%) Conclusion CTP is an effective imaging modality in detecting and diagnosing peritoneal metastases superior to plain CT更多还原
