中文摘要:
      目的 比较常规超声(包括灰阶超声、彩色多普勒血流显像、频谱多普勒超声)及超声弹性成像对良、恶性乳腺肿块的鉴别诊断价值。方法 对手术病理证实的475个乳腺病灶的常规超声、超声弹性成像图像进行回顾性分析,用ROC曲线评价其诊断价值。结果 超声弹性成像及常规超声诊断乳腺良恶性病灶的ROC曲线下面积(Az)分别为:0.959和0.899,差异有统计学意义(Z=2.7, P<0.01)。结论 在乳腺良恶性病灶的鉴别诊断方面,超声弹性成像的综合诊断价值优于常规超声。
英文摘要:
      Objective To compare the value of conventional ultrasonography (US, including gray-scale ultrasonography, color Doppler flow imaging and Doppler spectrum) and ultrasonic elastography (UE) in differentiating the benign and malignant breast lesions. Methods The static sonograms of US and UE of the 475 breast lesions which pathologically proved were reviewed. Receiver operating characteristic (ROC) curves were used to assess the diagnostic value of UE and US. Results The areas under the ROC curve (Az) of the two modalities were 0.959(UE) and 0.899(US), respectively. The difference between them was significant. Conclusion UE surpassed US in regard of the comprehensive diagnostic value for differentiating benign and malignant breast lesions.
