The purpose of this study was to evaluate pelvic masses by B-mode and Doppler ultrasonography for identification of ovarian malignancies.
A previously described scoring system for pelvic masses was applied in 310 women, and the lesions were classified into four groups according to the ultrasonographic structure. Pulsatility index values of vessels within the tumor and the contralateral ovary and of both uterine arteries were determined.
A total of 259 masses were benign and 51 were malignant. The scoring system and classification into morphologic groups revealed similar sensitivity, specificity, and positive and negative predictive values. Intratumoral and opposite ovarian blood flow and ipsilateral and contralateral uterine blood flow did not differ in benign and malignant masses except in cases of benign lesions in postmenopausal women. In malignant lesions a lower pulsatility index (0.94 +/- 0.4) was measured than in benign lesions (1.06 +/- 0.4, p < 0.05), although a remarkable overlap was found.
The results suggest that further refinement of assessment of pelvic masses with Doppler ultrasonography is needed.
本研究旨在通过B超和多普勒超声评估盆腔肿块，以识别卵巢恶性肿瘤。
对310名女性应用先前描述的盆腔肿块评分系统，并根据超声结构将病变分为四组。测定肿瘤内、对侧卵巢以及双侧子宫动脉的搏动指数值。
共有259个肿块为良性，51个为恶性。评分系统和形态学分组显示出相似的敏感性、特异性以及阳性和阴性预测值。除绝经后女性的良性病变外，良性和恶性肿块的肿瘤内和对侧卵巢血流以及同侧和对侧子宫血流并无差异。在恶性病变中，测得的搏动指数（0.94±0.4）低于良性病变（1.06±0.4，p<0.05），尽管存在明显重叠。
结果表明，需要进一步完善多普勒超声对盆腔肿块的评估。
