Objective: We report our experience to determine value of colored and pulsed Doppler sonography in diagnosing between benign and malignant ovarian tumors.

Methods: 64 patients with ovarian tumors were investigated by using of transabdominal and transvaginal sonography scanning with colored and impulse Doppler. Average age was years ranging from 35 to 65 yeas. The middle size of tumor was from 7 to 12 sm. During investigation intramural neovascularization zones were found out. Indices of blood supplying resistance (Rl - resistance index, PI - pulsatility index in ovarian, external and internal iliac arteriae), presence or absence of protodiastolic excision, minimal and maximal systolic speed were analyzed. All patients were operated by laparoscopy or laparotomy with further morphological investigation.

Results: Neovascularization zones were detected in 98% of malignant tumors and in 1.5% of benign tumors. Protodiastolic excision was observed in 89% of benign tumors. There were no cases of ones among malignant tumors. The middle range of Rl was 0.46±0.2 in malignant and 0.69±0.1 - in benign tumors. Sensitivity and specify were 86.2% и 86.7%, respectively. Correspondingly the middle ranges of PI were 1.08±0.06 и 0.5±0.12, with sensitivity 89.2% and specificity 90.4%. The summary of all blood supplying speeds has the best prognostic result with sensitivity 99% and specificity 85%.

Conclusions: The using of colored and impulse Doppler sonography provides to diagnosed of benign ovarian tumors during screening procedures.
