Abstract
Objective: The aim of this study was to evaluate the value of quantitative spectral Doppler ultrasound (DUS) flow measurements in ovarian tumors in postmenopausal women.
Material and Method: This prospective study included 23 postmenopausal women with preoperative diagnosis of ovarian tumor. Patients were examined with transvaginal DUS 2 to 4 days before surgery. 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, 13 benign and 1 borderline tumor. The mean RI and PI for malignant tumors were 0.37 (range 0.35-0.45) and 0.61 (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
