To assess the reliability of gray-scale and color and duplex Doppler ultrasound (US) in making a specific diagnosis of malignant ovarian tumor.
Forty-two women with 50 adnexal masses underwent endovaginal and color and duplex Doppler US. Morphologic characteristics were evaluated with endovaginal US, and flow velocity patterns were evaluated with color and duplex Doppler US. The results were compared with pathologic findings.
At pathologic examination, 40 masses (80%) were benign, one (2%) was borderline malignant, and nine (18%) were malignant. Endovaginal US enabled correct diagnosis of 38 of the 40 benign masses (95%) and all nine malignant masses (100%). Color and duplex Doppler US enabled correct diagnosis of 33 benign masses (82%) and seven malignant masses (78%).
Because there is an overlap in the resistive index (RI) values of benign and malignant masses, RI values alone cannot be relied on. Combining the detailed analysis of internal architectural appearance with the flow velocity patterns obtained at pulsed Doppler US increases the specificity in the diagnosis of adnexal masses.
评估灰阶、彩色及双功多普勒超声（US）对卵巢恶性肿瘤做出特异性诊断的可靠性。
42例患有50个附件包块的女性接受了经阴道彩色及双功多普勒超声检查。经阴道超声评估形态学特征，彩色及双功多普勒超声评估血流速度模式。将结果与病理结果进行比较。
病理检查显示，40个包块（80%）为良性，1个（2%）为交界性恶性，9个（18%）为恶性。经阴道超声能够正确诊断40个良性包块中的38个（95%）以及所有9个恶性包块（100%）。彩色及双功多普勒超声能够正确诊断33个良性包块（82%）以及7个恶性包块（78%）。
由于良性和恶性包块的阻力指数（RI）值存在重叠，不能仅依靠RI值。将内部结构外观的详细分析与脉冲多普勒超声获得的血流速度模式相结合，可提高附件包块诊断的特异性。
