探讨多层螺旋CT（MSCT）在女性盆腔非生殖源性肿瘤定位诊断中的应用价值。

回顾性分析2014年6月至2018年1月柳州市人民医院经手术病理证实的26例女性盆腔非生殖源性肿瘤患者的术前MSCT资料。重点观察肿瘤与周围邻近器官的关系（看病变细节）、供血来源（看血供）及病变侧卵巢显示情况（看病侧卵巢），评估上述征象在非生殖源性肿瘤中的定位诊断价值。

本组26例盆腔肿瘤，根据肿瘤与周围器官的关系判断病灶起源的准确性为80.8%（21/26），根据供血来源判断病灶起源的准确性为76.9%（20/26），病变侧卵巢显示情况判断病灶起源的准确性为53.8%（14/26）。

MSCT能清楚判断肿瘤与周围邻近器官的关系，能清楚显示肿瘤供血动脉及病变侧卵巢显示情况，综合运用三个指标（病变细节、血供、病侧卵巢）对肿瘤起源的判断具有重要意义。

To evaluate the application value of multi-slice spiral computed tomography (MSCT) in the localization of female pelvic non-reproductive tumors.

The preoperative MSCT data of 26 cases of female pelvic non-reproductive tumors confirmed by operation and pathology in Liuzhou People's Hospital from June 2014 to January 2018 were analyzed retrospectively, focus on the relationship between the tumor and surrounding organs (lesions in details), blood supply source (blood supply) and ovary of the affected side show (ovary of the affected side), to evaluate the localization diagnostic value of the above signs in non-reproductive tumors.

In 26 cases of pelvic tumors, according to the relationship between the tumor and surrounding organs, the accuracy of the origin of the lesion was 80.8% (21/26), the accuracy of the origin of the lesion was 76.9% (20/26) determined by the source of blood supply, and the accuracy of the origin of the lesion was 53.8% (14/26) determined by ovary of the affected side show.

MSCT can clearly determine the relationship between the tumor and surrounding organs, and can clearly show tumor feeding artery and the ovarian display of the lesion side. Comprehensive use of the three indicators (lesions details, blood supply, ovary of the affected side) is important for the judgment of tumor origin.
