摘要
为探讨磁共振成像（ＭＲＩ）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）均经手术、病理证实的卵巢肿瘤的ＭＲＩ及Ｂ超征象进行分析。计算各自的敏感性、特异性、准确性、并进行比较。表明ＭＲＩ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８８．１％／６１．９０％、９５．２％／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８０．９６％和５２．３８％（Ｐ＜０．０５），对恶性肿瘤的分期ＭＲＩ准确性达７７．８０％。显示ＭＲＩ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ＭＲＩ分期亦有较大价值。当然，ＭＲＩ目前尚存在检查费用高、时间长、实时性较差以及对某些肿瘤的组织定性有一定限度，有待进一步探索和改进。
his article reports 20 cases with obstructive jaundice caused solely by clonorchis sinensis clumps during the period of 1962 to 1993.All cases were misdiagnosed before operation.In order to raise the diagnostic rate,preoperative attention should be paid to the epidemic history,clinical features of the disease,which usually takes a longer course with fluctuating jaundice,and imaging characteristics of the fluke.Relief of biliary obstruction,drainage of bile and administration of helminthagogue are the principles is treatment of this diaeose.For those with a very clear out diagnosis,nonsurgical treatment is the first choice.
