经腹与经阴道超声对卵巢良恶性肿瘤鉴别诊断价值的对比研究

Differential diagnosis between benign and malignant ovarian tumor by color Doppler transabdominal ultrasound and transvaginal sonography

目的:探讨经腹与经阴道彩色多普勒超声(CD-TAS,CD-TVS)对卵巢肿瘤鉴别诊断的价值。方法:对手术切除病理检查的45例62个卵巢肿瘤的彩色多普勒超声及频普特征进行回顾性分析,将血流特征分型与临床病理分型对照。结果:恶性卵巢肿瘤组织中血流阻力指数(RI值0.38±0.05)显著低于良性卵巢肿瘤(RI>0.50),P<0.01,恶性卵巢肿瘤中RI值特异性达83.3%(15/18),交界性的卵巢瘤RI值0.40～0.50,良性卵巢瘤RI值特异性达97.7%(43/44)。结论:CD-TVS检查的符合率优于CD-TAS检查,彩色多谱勒血流显像与频谱特征对卵巢肿瘤的性质预测具有一定的临床意义。

Objective： To discuss the value of differential diagnosis of color Doppler transabdominal ultrasound （ CD - - TAS） and color Doppler transvaginal sonography （CD- -TVS） in ovarian tumors. Methods： The authors retrospectively analyzed color Doppler sonography and the spectra in 45 cases with 62 ovarian tumors confirmed by pathology and surgery, and compared the flow types with clinical pathology. Results ： The resistance index （RI） of the malignant group （ RI = 0. 38 ± 0. 05 ） was significantly lower than that of the benign group （ RI 〉0. 50, P 〈0.01 ） . The specificity of RI in malignant group, interfacial group, and benign group was 83, 3% （15/18） , 0. 40 -0. 50 and 97.7% （43/44） respectively. Conclusion： CD -TVS has a higher coincidence rate than that of CD -TAS, and the spectral characteristics can be applied to forecast the quality of ovarian tumors.
