TRANSVAGINAL DOPPLER ULTRASOUND QUANTITATIVE FLOW MEASUREMENTS OF OVARIAN TUMORS IN POSTMENOPAUSAL WOMEN

Purpose: The aim of this study was to evaluate the value of quantitative spectral Doppler ultrasound (DUS) flow measurements in ovarian tumors in postmenopausal women. Methods and Materials: This prospective study included 23 postmenopausal women with preoperative diagnosis of the ovarian tumor. Patients were examined with transvaginal DUS 2 to 4 days before surgery. The surgeon and the pathologist who examined the specimens were blinded to the DUS examination. The resistive index (RI) and pulsatility index (PI) of the mass were evaluated by transvaginal DUS examination. Results: The histopathologic examination of the surgical specimens revealed 8 malignant, 14 benign and 1 borderline tumor. The mean RI and PI for malignant tumors were 0.37 (range 0.35–0.45) and 0.59 (range 0.43–0.85), respectively. The mean RI and PI for benign tumors were 0.61 (range 0.30–0.91) and 1.21 (range 0.36–3.02), respectively. The Mann-Whitney U test revealed a statistically significant (p
