Abstract
Retrospective analysis of pelvic sonograms with color-guided spectral Doppler evaluation
of 189 adnexal masses yielded four malignancies, 20 benign neoplasms, 32 cysts, and
14 endometriomas. Fifty-eight masses were presumed benign on additional imaging. Pulsatility
index (PI) < 1.0 was seen in 70% neoplasms, 63% benign cysts and 50% endometriomas.
Thirteen percent of benign cysts and no neoplasms had resistive index (RI) < 0.4.
Fifty percent malignancies had PI < 1.0. None had RI < 0.4. Both thresholds lack sufficient
sensitivity and specificity for distinguishing benign and malignant lesions.
