Methods 96 patients pelvic masses were studied by transvaginal ultrasonograph mass scoring, and by CDFI through pulsatility index (PI) and resistance index (RI) of peripheral blood flow of mass analyses. Results Mass ultrasonic scoring : scoring >9, 91.9% masses were malignant tumors. Scoring ≤<9, 91.5% masses were benign tumors. PI and Rl of peripheral blood flow of masses were detected by CDFI: Pl< 1 .0 . 92.5% cases; RI<0.5, 97.4% cases were malignant tumors. The diagnosis match rate of malignant ovarian tumors was 97.0% . The diagnosis match rate of benign ovarian tumor was 96 .2% . The diagnosis match rate was improved. Conclusion Ovarian mass ultrasonic scoring>9 and PI< 1 .0 , RI<0 .5 of mass peripheral blood flow are the special ultrasonic features of malignant ovarian tumor and the better methods to distinguish the benign ovarian tumor from the malignant one.展开更多
