经阴道三维能量多普勒超声定量分析卵巢肿块的良恶性

Quantitative Analysis of Malignant and Benign Ovarian Masses with Transvaginal Three- dimensional Power Doppler Ultrasound

目的探讨经阴道三维能量多普勒超声(three-dimensional power Doppler transvaginal ultrasound,3DPD-TVS)定量分析卵巢肿块血流灌注参数并评估其鉴别卵巢肿块良恶性的价值.方法应用3DPD-TVS对101个卵巢肿块进行检查并测量以下参数:阻力指数(resistance index,RI)、血管化指数(vascularization index,VI)、血流指数(flow index,FI)、血管化血流指数(vascularization flow index,VFI),分析数据并与术后病理结果对照.结果卵巢肿块恶性组VI、FI、VFI值明显高于良性组[(1.57±2.37)vs(5.10±4.68)、(35.53±7.91)vs(40.92±6.82)、(0.61±0.99)vs(2.18±2.06)],差异有统计学意义(P<0.05);而2组间比较,RI无明显差异(P>0.05).结论经阴道三维能量多普勒超声能较客观定量分析卵巢肿块的血供情况,为鉴别卵巢肿块良恶性提供一定的参考价值.

Objective To investigate the effect of three- dimensional power Doppler transvaginal ultrasound（ 3DPD- TVS） quantitative analysis of ovarian masses perfusion parameters and evaluate the value of it in identification of the malignant and benign ovarian masses. Methods 101 ovarian masses were examined with3DPD- TVS and the corresponding parameters： the resistance index（ RI）, vascularization index（ VI）, flow index（ FI）,vascularization flow index（ VFI） were analyzed. Then the results were compared with the postoperative pathological results.Results VI, FI, VFI values with ovarian malignant tumor group were significantly higher than those in benign tumor group, the difference was statistically significant（ P〈0.05）. RI showed no significant difference between malignant tumor group and benign masses group（ P〈0.05）.Conclusion Transvaginal three- dimensional power Doppler ultrasound can be used to objectively and quantitatively analyze of ovarian masses and provide certain reference value for the identification of malignant and benign ovarian masses.
