目的探讨高频彩色多普勒超声对乳腺癌的诊断价值。方法分析95例乳腺癌二维高频声像图及彩色多普勒血流情况,与手术病理结果对照。结果高频彩色多普勒超声检查确诊86例,误诊9例,诊断符合率90.5%。典型的乳腺癌超声特征为:实性低回声包块,形态多不规则,呈“蟹足样”或“毛刺样”,边界不清,内部回声不均,可伴沙砾样钙化光点,后方回声衰减,纵横比大于1,彩色多普勒血流分级为Ⅱ￣Ⅲ级77例(81%),Vmax>20cm/s70例(73.7%),RI>0.768例(71.6%)。超声误诊9例中7例因直径<2cm,无典型二维图像特征,CDFI未测及明显血流信号。另2例因无瘤体回声而误诊为炎性病变。结论综合分析乳腺癌的二维及彩色血流特点,可提高乳腺癌的诊断率。但对<2cm的小乳癌的诊断应要更加警惕,必要时做组织学检查,减少误诊。
Objective To investigate the diagnostic value of high frequency color Doppler ultrasound in breast cancer. Methods 95 cases of breast cancer two-dimensional high-frequency ultrasonography and color Doppler flow was compared with the surgical pathology results. Results High-frequency color Doppler ultrasound confirmed 86 cases, misdiagnosed 9 cases, the diagnostic coincidence rate of 90.5%. A typical breast ultrasound features: solid hypoechoic mass, irregular shape, was “crab-like” or “burr-like”, the boundary is unclear, the internal echo uneven, with gritty calcified spots, the rear Echo decay, aspect ratio greater than 1, color Doppler flow grade Ⅱ ~ Ⅲ grade 77 cases (81%), Vmax> 20cm / s70 cases (73.7%), RI> 0.768 cases (71.6%). Ultrasound misdiagnosis in 9 cases, 7 cases due to diameter <2cm, no typical two-dimensional image characteristics, CDFI not detected and significant blood flow signal. The other 2 cases were misdiagnosed as inflammatory lesions due to tumor-free echo. Conclusion The comprehensive analysis of two-dimensional and color flow characteristics of breast cancer can improve the diagnosis rate of breast cancer. However, the diagnosis of small breast cancer <2cm should be more vigilant, if necessary, do histological examination to reduce misdiagnosis.
