摘要
目的:探讨MRI对卵巢良恶性疾病的鉴别诊断价值。方法:分析66例经手术病理证实的卵巢疾病的MRI特征,良性病变36例,其中卵巢囊肿7例,巧克力囊肿5例,畸胎瘤10例,炎症肿块4例,浆液性囊腺瘤6例,粘液性囊腺瘤4例;恶性病变30例,其中浆液性囊腺癌10例,粘液性囊腺癌11例,内胚窦瘤4例,Krukenberg’s肿瘤5例。所有患者行常规扫描,平扫发现病灶行增强扫描,术后对所有病变行MR征象与病理结果对照分析。结果:MRI检查能很好显示卵巢病变的特征,其定位诊断100%,诊断的敏感性93%,特异性94%,准确性94%,卵巢癌分期准确性达85.0%。结论:MRI对卵巢良恶性病变的鉴别诊断价值大,并可提供卵巢癌分期所需的信息,增强扫描可进一步提高MR对卵巢癌的诊断及分期的准确性。
Objective: To evaluate MRI diagnostic values in differentiation benign with malignant ovarian lesions. Methods: MRI features of 66 cases with histologically proven ovarian lesions were retrospective reviewed, including ovarian cysts (n = 7), chocolate cysts ( n = 5 ), teratoma( n = 10 ), inflammation( n = 4), serous cystadenoma ( n = 6), mucinous cystadenoma ( n = 4), serous cystadenocarcinoma (n = 10), mucinous cystadenocarcinoma (n = 11 ), endedermal sinus tumor (n = 4), Krukenberg' s tumor (n = 5). All of cases underwent MR and MR enhancement scan. Results:MRI can accurately judge the character of ovarian disease. The localized diagnosis of lesions was up to 100%. The sensitivity, specificity and accuracy of MRI diagnosis were 93%, 94%, 94% respectively. The accuracy of staging of ovarian carcinoma was up to 85.0%. Conclusion:MRI had a great value in differentiation from malignant and benign ovarian lesions. Furthermore MRI was of great value in staging of ovarian carcinoma especially with MRI enhancement.
