本文探讨ＭＲ和Ｂ超对卵巢肿瘤良恶性鉴别、定性及恶性肿瘤分期的诊断价值。采用双盲法对４２例（４９个病灶）经手术、病理证实的卵巢肿瘤的ＭＲ及Ｂ超征象进行分析。结果：ＭＲ和Ｂ超对卵巢肿瘤良恶性鉴别的敏感性、特异性、准确性分别为８８．１０％／６１．９０％；９５．２４％／７１．４３％；９１．６７％／６６．６７％．两者间存在显著差异（Ｐ＜０．０５），定性准确性分别为８０．９５％和５２．３８％（Ｐ＜０．０５）。对恶性肿瘤的分期ＭＲ准确性达７７．８％。ＭＲ扫描对卵巢肿瘤良恶性鉴别、定性均优于Ｂ超，对恶性肿瘤的分期亦有较大价值。
This article discusses the diagnostic value of MR and B ultrasonography in differential diagnosis of benign and malignant ovarian tumors, as well as the qualitative and malignant tumor staging. The double-blind method was used to analyze the MR and B-ultrasound findings of 42 cases (49 lesions) of surgically and pathologically confirmed ovarian tumors. Results: The sensitivity, specificity and accuracy of MR and B-ultrasound in differentiating benign and malignant ovarian tumors were 88.10% / 61.90%, 95.24% / 71.43% and 91.67% / 66 respectively. 67%. There was significant difference between the two (P <0.05), the qualitative accuracy was 80.95% and 52.38% (P <0.05). Malignant tumor staging MR accuracy of 77.8%. MR scan of benign and malignant ovarian tumor identification, qualitative better than the B, the staging of malignant tumors have great value.
