彩色多普勒超声与CT诊断女性盆腔肿块的对比研究

Comparative study of color doppler ultrasonography and CT in diagnosis of female pelvic mass

目的:探讨彩色多普勒超声及CT检查在女性盆腔良恶性肿块的诊断及鉴别诊断的应用价值。方法:回顾性分析经手术病理证实的146例女性盆腔肿块的彩色多普勒超声(CDUS)检查,部分病例同时行CT检查的影像学资料。结果:(1)CDUS与病理结果的一致性Kappa系数为0.744(P<0.01),CT与病理结果的一致性Kappa系数为0.774(P<0.01)。(2)CDUS判断盆腔肿块性质的符合率为89.04%;CT判断盆腔肿块性质的符合率为89.13%。其诊断符合率之间的比较其差异无统计学意义(P>0.05)。结论:CDUS与CT检查在诊断盆腔肿块方面均具有较高的诊断价值,但因CDUS检查具有简单易行、重复性好、经济、无辐射等优点,可作为诊断盆腔肿块以及术前、术后动态观察的首选方法;CT可作为CDUS疑盆腔恶性肿块的重要补充影像学检查方法,以提高盆腔恶性肿瘤的诊断符合率。

Objective： To explore the clinical values of color doppler ultrasound and CT examination in the diagnosis and differential diagnosis of benign and malignant pelvic tumors in females. Methods： Image data by color doppler ultrasound（CDUS） in 146 cases of female pelvic masses and some patients by CT,which were confirmed by operation and pathology, were retrospectively analyzed. Results： 1. The Kappa consistency coefficient between CDUS and the pathological results was 0.744（P〈0.01）,while the Kappa consistency coefficient between CT and the pathological results was 0.774（P 〈0.01）. 2. The coincidence rate of CDUS examination for pelvic tumors was 89. 04%,and the rate of CT examination was 89. 13%.There was no statistical difference of the diagnostic coincidence rate between the two methods（P〉0.05）.Conclusion： CDUS and CT examinations have high clinical values in the diagnosis of pelvic masses.Because CDUS has the advantages of being simple to operate, good repeatabilty, economy and no radiation,it can be the preferred examination in the diagnosis,preoperative and postoperative dynamic observations; while CT can be used as important supplement examination method of CDUS suspected malignant pelvic tumor for improving the diagnostic coincidence rate of pelvic malignant tumor.
