[Transvaginal color Doppler in ovarian neoplasms]

Thirty one patients with clinical and sonographic diagnosis of ovarian tumor were studied prospectively, with Transvaginal Color Doppler. There were 24 benign and 7 malignant tumors (4 stage I borderline, I stage IA cistoadenocarcinoma and 2 adenocarcinoma stage III). Six malignant tumors had resistance indexes (IR) from 0.17 to 0.55. In one borderline no vascular signal was obtained. The probability of malignancy increased inversely with the IR from 60%, with RI below 0.60 to 100% with IR below 0.4.
