【摘要】目的 探讨彩色多普勒血流显像鉴别乳腺肿块的诊断价值。方法 对80个乳腺肿块患者进行超声检查，对比分析良、恶性肿块的二维超声特点、彩色血流情况及血流动力学参数的特征。结果 乳腺恶性肿块的CDFI血流信号较良性肿块明显丰富，恶性肿块的PI、RI值明显高于良性肿块，两组对比有统计学意义(P<0.05)。结论 彩色多普勒超声作为无创的检查方法，可清晰显示肿块的二维声像图特点和血流动力学特征，对乳腺肿块的鉴别具有重要临床应用价值。

    [Abstract] Objective To investigate the value of color Doppler flow imaging in the diagnosis of breast masses. Methods 80 cases of breast masses were examined by ultrasonography， the characteristics of two-dimensional ultrasound， color flow and hemodynamic parameters were compared and analyzed. Results the CDFI blood flow signal of breast malignant tumor was significantly higher than that of benign tumor ......
