Sutanthavibul A The purpose of this cross-sectional study was to evaluate whether the pulsatility index
determined by the color Doppler sonography could be used to distinguish between benign and
malignant ovarian tumors. A total of 120 patients who had their ovarian tumors removed surgically
at the Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital, Mahidol Uni-
versity were included in the study. Each patient had color Doppler sonography performed prior to
laparotomy. The Doppler results were compared to the histological diagnosis of the ovarian tumors.
Of the 113 patients whose intratumoral blood flow could be evaluated, the pulsatility index was
significantly lower in malignant lesions than in benign lesions (0.85
