Comparison of resistive index versus pulsatility index in assessing the benign etiology of adnexal masses.

Abstract：

:Retrospective analysis of pelvic sonograms with colorguided 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.
