摘　　要：目的探讨DWI联合常规MRI序列,在卵巢癌上腹部腹膜转移瘤的诊断价值。方法回顾性分析39例可疑腹膜转移的卵巢癌患者上腹部MRI资料,分为常规MRI和DWI联合常规MRI两组读片。将病变按解剖部位进行观察,记录转移瘤的有无。并与手术病理结果或随访证实结果对比,分析两组诊断卵巢癌上腹部腹膜转移的敏感性,特异性和准确性。结果DWI联合常规MRI能显著提高转移瘤检出率,检出了117个部位,敏感性94%,准确性94%(P<0.05);而常规MRI序列检出了99个部位,敏感性79%,准确性86%(P<0.05)。结论在常规MRI扫描序列的基础上,增加DWI序列,能够显著提高上腹部卵巢癌腹膜转移瘤检出的敏感性及准确性。Objective To assess the value of combined DWI and conventional MRI in diagnosis of peritoneal carcinomatosis from ovarian cancer in upper abdomen.Methods MR images of 39 ovarian cancer patients with suspected peritoneal carcinomatosis were reviewed in conventional MRI group and combined DWI and conventional MRI group respectively.We analyzed the sensitivity,specificity and accuracy of two groups compared with the standard of reference.Results Totally,117 anatomic peritoneal sites involved by tumor were detected in combined group,with the sensitivity of 94%,specificity of 94%,while,99 were detected in conventional group,with the sensitivity of 79%,specificity of 86%.Both sensitivity and specificity were significantly higher in the combined group than in the conventional group(P<0.05).Conclusion DWI combined conventional MRI can increase the sensitivity and specificity in detection of the peritoneal carcinomatosis from ovarian cancer in upper abdomen.
