CT和MRI对卵巢肿瘤的诊断价值比较

目的:研究卵巢肿瘤的CT、MRI表现,比较CT与MRI对卵巢肿瘤的诊断价值。材料与方法:回顾分析经手术病理证实的84例卵巢肿瘤的临床及影像学资料。病变经CT检查51例(62个肿块),经MRI检查33例(42个肿块),同时经CT和MRI检查者25例。结果:CT、MRI对卵巢肿瘤诊断的准确性、敏感性和特异性分别为87.1%对95.2%,89.4%对96.9%,80%对90%,经χ2检验均无显著性差异(P>0.05),但MRI对卵巢肿瘤的定位与定性诊断价值优于CT(P<0.05)。结论:CT与MRI对卵巢肿瘤具有重要诊断价值,MRI对卵巢肿瘤的检出与定性诊断价值优于CT。

Comparative study of CT and MRI in the diagnosis of ovarian neoplasms

Objective: To study the manifestations of ovarian neoplasms on CT and MRI,and compare the diagnostic significance of CT and MRI for ovarian neoplasms. Materials and Methods: Clinical and radiological data of 84 cases with ovarian neoplasms proved histopathologically were retrospectively reviewed. In this series,51 patients(62 ovarian masses) were studied by CT and 33 patients(42 ovarian masses) by MRI,25 patients by both CT and MRI. Results: The accuracy,sensitivity and specificity of CT and MRI in detection of ovarian neoplasms were 87.1% vs 95.2%,89.4% vs 96.9%,80% vs 90%,respectively,no significant difference were found among them by chi-square test(P>0.05),but the diagnostic value of MRI in localization and characteristics of ovarian neoplasms was superior to that of CT(P<0.05). Conclusion: There is obviously diagnostic value for ovarian neoplasms with CT and MRI,MRI is superior to CT in lesion detection and qualitative diagnosis of ovarian tumors.
