    Abstract:
    The impedance to blood flow was examined by transvaginal color flow imaging in 53 ovarian masses before exploratory laparotomy. Serum CA 125 levels were measured in all subjects. Thirty-six had benign ovarian tumors and 17 had malignant ovarian tumors confirmed by histopathologic examination. Intratumoral blood vessels, detected in 16 of the malignant tumors, consistently demonstrated low impedance to flow, with a pulsatility index (PI) always below 1. The PI of the intraovarian or intratumoral blood vessels was greater than 1 in 35 of the 36 benign tumors, although 11 had suspicious sonographic findings (P less than .01) and 14 had elevated CA 125 levels (P less than .001). The sensitivity and specificity of the preoperative PI in detecting malignant ovarian tumors were 94 and 97%, respectively. The sensitivity and specificity of preoperative suspicious sonographic findings in detecting malignant ovarian tumors were 94 and 69%, and those of elevated preoperative serum CA 125 levels were 82 and 61%, respectively. Our results suggest that transvaginal color flow imaging may be a useful clinical tool in the preoperative evaluation of ovarian masses.
