摘要
目的探讨ADC值鉴别附件区含实性成分肿块良恶性的鉴别诊断价值。方法 76例行DWI序列(b=0、1000 s/mm^2)的含实性成分的附件区肿块纳入研究,恶性肿瘤38例,交界组12例,良性组26例。采用多个独立样本非参数Kruskal-Wallis H检验进行三组之间ADC值的比较。采用ROC曲线分析ADC值诊断附件恶性病变的诊断效能。结果恶性、交界性及良性三组之间ADC值存在统计学差异(P<0.001),恶性组与交界组、良性组均存在统计学差异(P<0.001),交界组与良性组之间无统计学差异(P=0.818)。经ROC曲线分析,ADC值诊断附件恶性病变的曲线下面积为0.956,敏感度、特异度为97%、92%;ADC值诊断附件交界性病变的曲线下面积为0.79,敏感度、特异度为92%、64%。结论 ADC值对于附件区含实性成分肿块的鉴别诊断具有一定的作用,尤其对恶性病变具有较高的诊断价值,ADC值对交界组与良性病变的鉴别诊断价值不大。
Objective To assess the diagnostic value of apparent diffusion coefficient(ADC) for adnexal mass with solid component. Methods 76 women with 38 adnexal malignancy, 12 borderline ovarian tumors, and 26 benign adnexal lesions underwent diffusion-weighted imaging(DWI) with b=0 and 1000 s/mm^2. The Kruskal-Wallis H test was used to compare the ADCs among the three groups. The diagnostic performances were calculated using the receiver operating characteristic(ROC) curve analysis.Results The mean ADC value of malignancy was significantly lower than that of borderline tumors and benign masses( P<0.001).There was no statistical significance between the mean ADCs of benign and borderline masses( P = 0. 818). The diagnostic sensitivity,specificity, and area under the ROC curve were 97%, 92%, 0.956 for malignancy; 92%, 64%, 0.790 for borderline tumors.Conclusion ADC value is useful in distinguishing malignant from benign or borderline adnexal masses with solid components.
