摘    要:目的 探讨卵巢良恶性肿瘤的彩色多普勒超声血流形态学和血流动力学特征。方法 对95例患者105个卵巢病变,用能量多普勒观察肿物内的血流形态学改变(包括血管的分级,血管是否有畸形),用脉冲多普勒检测肿瘤内的血流动力学。观测指标:收缩期峰值流速(VPS)、舒张末期流速(VεD)、平均流速(VM)、搏动指数(PI)、阻力指数(RI)及是否存在舒张期切迹。用逐步回归的方法对上述指标进行分析。结果 所观测的血流形态学及动力学各指标在良恶性卵巢肿瘤之间的差异均存在显著性意义。逐步回归显示,RI的意义最大。RI界值定为0.51时,其鉴别良恶性卵巢肿瘤的敏感性和特异性分别为98.0%,96.2%。结论 RI是鉴别卵巢肿瘤良恶性质的最有意义的血流动力学指标。

关 键 词:彩色多普勒超声  卵巢肿瘤  诊断  血流形态学  血流动力学

Abstract:Objective To observe and measure the Doppler sonographic features of benign and malignant ovarian neoplasms,which included morphology and hemodynamics of tumor angiogenesis,and to select the most significant features. Methods Ninety-five patients with one hundred and five ovarian tumors were examined preoperatively by power Doppler sonography to observe the morphology of tumor angiogenesis. The hemodynamic features of tumor angiogenesis referred for pulsed Doppler sonography evaluation were measured,which included peak systolic velocity(V PS ),end diastolic velocity(V ED ),mean flow velocity(V M),pulsatility index(PI),resistance index(RI) and diastolic notch. To assess the variables jointly,stepwise regression analysis was used to identify the group of features that allowed the best prediction of benignity versus malignancy. Results All Doppler features significantly associated with malignancy .The ROC curve of RI revealed that the cutoff of RI( 0.51 ) with the highest accuracy had a sensitivity of 98.0 % and specificity of 96.2 %.Conclusions RI was most significantly associated with malignancy. The combination of RI and gray-scale sonography can maximize the ability to discriminate between benign and malignant ovarian tumors.
Keywords:Ultrasonography  Doppler  Ovarian neoplasms  Hemodynamics
