Color duplex sonography in evaluating ovarian masses

ABSTRACT

Color duplex was used to evaluate 16 cases of clinically or ultrasonographically diagnosed ovarian masses. Flow pattern and resistance index [RI] and pulsatility index [PI] were calculated in every case. Results have shown that all benign ovarian masses had PI >1 and RI >0.5. On the other hand, 75% of malignant lesions had PI <1 and RI <0.5. These results show that color doppler can be useful in excluding malignant tumors but not in confirming its presence
