摘　　要：目的探讨上皮来源卵巢恶性肿瘤的超声和MRI征象,对比两种影像检查方法的诊断价值。方法回顾性分析我院经手术病理证实的80例上皮来源卵巢肿瘤患者经阴道的二维超声表现和彩色多普勒能量图,同时总结分析其MRI征象,对比分析超声和MRI检查的诊断价值。结果二维超声显示良性病灶形态规则、包膜连续,内部回声囊性为主,少有乳头及腹腔积液,血流成像(Color Doppler Flow Imaging,CDFI)显示乏血供为主;恶性病灶表现为形态不规则、包膜不连续,内部回声实性为主,乳头及腹腔积液多见,CDFI显示富血供为主。MRI显示良性病灶形态规则、边界清、囊性为主、信号多均匀、多无强化、少腹腔积液、周围器官不受累、无淋巴结转移;恶性病灶形态不规则、边界不清、实性为主、信号不均匀、均有强化、多腹腔积液、周围器官受累、有淋巴结转移。结论MRI联合经阴道超声及CDE检查可有效提升上皮来源卵巢恶性肿瘤的诊断准确率。而且当上皮来源卵巢恶性肿瘤不典型或病灶较小时,两种方法相联合更佳。Objective To investigate the ultrasonographic and MRI features of epithelial ovarian malignant tumors,and to compare the diagnostic value of the two imaging methods.Methods The transvaginal two-dimensional ultrasound manifestations and color Doppler energy maps of 80 patients with epithelial ovarian tumors confirmed by surgical pathology in our hospital were analyzed retrospectively.The signs of MRI were summarized and analyzed,and the diagnostic value of ultrasound and MRI were compared and analyzed.Results Two-dimensional ultrasound showed that benign lesions had regular shape and continuous capsule,with cystic internal echo and few nipple and peritoneal effusion,color Doppler flow imaging(CDFI)showed poor blood supply.The malignant lesions showed irregular shape and discontinuous capsule,internal echo solidity mainly,nipple and peritoneal effusions were more common,and CDFI showed rich blood supply.MRI showed that benign lesions had regular shape,clear boundary,mainly cystic,more homogeneous signal,less peritoneal effusion,no involvement of surrounding organs,no lymph node metastasis,while malignant lesions had irregular shape,unclear boundary,mainly solid,uneven signal,all enhanced,multiple abdominal cavity effusion,peripheral organs involved,lymph node metastasis.Conclusion MRI combined with transvaginal ultrasound and CDE examination can effectively improve the diagnostic accuracy of epithelial ovarian malignant tumors.Moreover,when the epithelial ovarian malignant tumor is not typical or the lesion is small,the combination of the two methods is better.
