目的 探索卵巢静脉追踪结合MPR在CT识别卵巢源肿物中的应用价值.方法 收集2014年9月~2015年8月在我院进行腹盆部CT增强检查、随后进行手术并取得病理结果的女性盆腔肿物患者234例.两位放射科医师采用卵巢静脉追踪结合MPR的方法识别盆腔肿物是否为卵巢来源.以手术及病理结果为金标准,计算该方法识别卵巢源肿物的敏感性、特异性、准确性、阳性预测值、阴性预测值.结果 被观察病例234例,盆腔肿物共283个.217个卵巢源肿物中,CT诊断正确208个,66个非卵巢源肿物中,CT诊断正确53个.采用卵巢静脉追踪结合MPR的方法,CT识别卵巢源肿物的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为95.9%、80.3%、92.2%、94.1%、85.5%.结论 采用卵巢静脉追踪结合MPR的方法在CT上识别卵巢源肿物的准确性很高.这种方法在实际工作中有很大的应用价值,值得推广.%Objective To explore the value of ovarian vein tracing combined with MPR in recognition of ovarian origin masses with CT. Methods Female patients with pelvic masses who had undergone both contrast-enhanced CT examination in our hospi-tal and following surgeries from Sep. 2014 to Aug. 2015 were collected. A total of 234 cases were included. All the CT diagnoses were confirmed by surgery and pathologic results. CT and MPR images were analyzed by two radiologists before surgery. Ovarian origin masses and non ovarian origin masses were identified by tracing ovarian vein on CT continuing images and MPR images. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of recognition of ovarian origin mas-ses through this method were calculated. Results In total 234 cases, there were 283 pelvic masses including 217 ovarian origin masses and 66 non ovarian origin masses. 208 ovarian origin masses and 53 non ovarian origin masses were accurately diagnosed by CT. Through the method of ovarian vein tracing combined with MPR, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of identification of ovarian origin masses were 95. 9%, 80. 3%, 92. 2%, 94. 1%, and 85. 5%, respectively. Conclusion The method of ovarian vein tracing combined with MPR helps to identify ovarian origin mas-ses and non ovarian origin masses on CT and has great application value in clinical practice.
