MRI和B超对卵巢肿瘤的诊断和比较

Comparison of MRI and Ultrasound in Diagnosis of Ovarian Neoplasms

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。

To investigate the accuracy of MR imaging and Ultrasound in the differentiation characterization of ovarian mares and staging of malignant neoplasms. Double bliading analyzed imagings of MR and ultrasound in 42 patients (49masses). Findings were confirmed at surgery and path -- histology and then compared with findings Of MR imaging and ultrasound. Result: The sesitivity specifity and accuracy of MR imaging and ultraseund in the differentiation of overman masses wererespectively 88. 10%/61. 90% . 95. 24 %/71. 43 % .91. 67%/66. 67%. (all p < 0. 05 ). In characterization of varian neoplasms, the accuracy of MR imaging and ultraseund was 80. 95 % and 52. 38 % (p< 0. 05). The 77. 8% of accuracy was atlained with MR imaging in staging of malignant neoplasms. Conclusion: MR imaging is superior to B mode ultrasound in thedifferentiation and characterization of ovarian masses as well as great value in the staging of malignant neoplasms.
