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.
