Transvaginal color Doppler sonography of adnexal masses: differences in blood flow impedance in benign and malignant lesions.

Abstract

Our preliminary data suggest that high pulsatility and resistive indexes indicate benign adnexal processes; however, considerable overlap in pulsatility and resistive indexes between benign and malignant lesions was noted, and further work is needed before the validity of these factors is proved.
