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.
对189例附件包块进行彩色引导频谱多普勒评估的盆腔超声检查结果进行回顾性分析，发现其中有4例恶性肿瘤、20例良性肿瘤、32例囊肿和14例子宫内膜瘤。另外58个包块经其他影像学检查推测为良性。在肿瘤中，70%的搏动指数（PI）<1.0，良性囊肿中63%、子宫内膜瘤中50%的PI<1.0。13%的良性囊肿阻力指数（RI）<0.4，而肿瘤中无此情况。50%的恶性肿瘤PI<1.0，无一例RI<0.4。这两个阈值在区分良性和恶性病变方面均缺乏足够的敏感性和特异性。
