Eighty-seven women with mammographically suspicious breast lesions were investigated prior to surgery. 32 breast carcinomas and 55 benign lesions were evaluated for the resistance index, the pulsatility index, the flow velocity and the acceleration index. Our study showed the resistance index with a threshold value of 0.70 to be best suited to differentiate benign tumors from malignant ones. In this series, the sensitivity of color Doppler ultrasonography for the detection of breast carcinomas was 84%, and the specificity 80%. The positive predictive value was 71% and the negative predictive value 90%. Color Doppler scanning offers one possible method for further investigation of patients with mammographic abnormalities and can help to reduce the number of unnecessary breast biopsies.
87名乳房X光检查显示有可疑乳腺病变的女性在手术前接受了检查。对32例乳腺癌和55例良性病变进行了阻力指数、搏动指数、流速和加速度指数的评估。我们的研究表明，阈值为0.70的阻力指数最适合区分良性肿瘤和恶性肿瘤。在本系列研究中，彩色多普勒超声检测乳腺癌的敏感性为84%，特异性为80%。阳性预测值为71%，阴性预测值为90%。彩色多普勒扫描为进一步检查乳房X光异常的患者提供了一种可能的方法，有助于减少不必要的乳房活检数量。
