多排螺旋CT对卵巢源性与非卵巢源性肿瘤的鉴别诊断价值

目的 探讨多排螺旋CT(MSCT)在卵巢源性与非卵巢源性肿瘤鉴别诊断中的价值.方法 回顾性分析55例盆腔肿瘤患者MSCT资料,分析MSCT卵巢血管蒂征、卵巢显示征、肿块与输尿管位置关系在卵巢源性与非卵巢源性盆腔肿瘤鉴别诊断中的价值,并以病理学结果为金标准,计算MSCT诊断卵巢源性肿瘤的灵敏度、特异度及准确度.结果 卵巢源性肿瘤卵巢血管蒂征阳性率为70.97%,高于非卵巢源肿瘤的8.33%(P<0.05);卵巢显示征阳性率为6.45%,低于非卵巢源肿瘤的66.67%(P<0.05);卵巢源性肿瘤位于输尿管前为100%,高于非卵巢源肿瘤的87.5%(P<0.05).MSCT诊断卵巢源性肿瘤敏感度、特异度及准确率分别为90.32%、91.67%、90.91%.结论 MSCT在卵巢源性与非卵巢源性肿瘤的鉴别诊断中与病理诊断结果具有较好的一致性,卵巢血管蒂征、卵巢显示征、肿块与输尿管位置关系可作为其鉴别诊断依据.

Differential diagnosis value of multi-slice spiral CT between ovarian and non-ovarian tumor

Objective To investigate the differential diagnosis value of multi-slice spiral CT(MSCT) between ovarian and non-ovarian tumor.Methods A retrospective analysis was made on the MSCT data of 55 cases of pelvic tumor patients.Value of ovarian vascular pedicle syndrome,ovarian show character,and position relationship of mass and ureter in distinguishing ovarian and non-ovarian tumor were analyzed,and sensitivity,specificity,and accuracy of MSCT in the diagnosis of ovarian tumor were calculated on account of the pathological gold standard . Results The positive rate of ovary vascular pedicle syndrome in ovarian tumor patients was 70.97%,significantly higher than 8.33% of non-ovarian tumor patients(P<0.05).The positive rate of ovarian show character in ovarian tumor patients was 6.45%,significantly lower than 66.67%of non-ovarian tumor patients ( P<0.05).The ovarian tumors located in front of the ureter was 100% in ovarian tumor patients,significantly higher than 87.5%of non-ovarian tumor patients(P<0.05).The sensitivity,specificity and accuracy in differential diagnosis of ovarian and non-ovarian tumor by MSCT were 90.32%,91.67%,90.91% in sequence.Conclusion MSCT has a good coherence with pathological gold standard in differential diagnosis of ovarian and non-ovarian tumor ,and ovarian vascular pedicle syndrome , ovarian show character ,and position relationship of mass and ureter can be used as evidences for its differential diagnosis .
