Objective : The aim of the study was to evaluate the effectiveness of doppler flow sonography for the discrimination between benign and malignant ovarian masses and to find out the best resistance index (RI) cut off value. Materials and Methods : In a cross-sectional study 194 patients with adnexial masses were examined using Doppler sonography to measure the resistance index of tumor associated blood flow profiles preoperatively. Results : Seventy-four had malignant tumors, 120 had benign tumors. RI values were ranging from 0.27 to 0.87 and from 0.35 to 1.0 in malignant and benign tumors respectively (p<0.001). Conclusion : Doppler flow measurements are effective in the differentiation of benign and malignant adnexial masses. Discriminatory zone for the RI is found to be between 0.5 and 0.6,but there is still overlapping between malignant and benign cases and this can be reduced by using tumor markers and two dimensional morphological assesment.
