目的:研究高频彩色多普勒超声对乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结的鉴别价值。方法:选择2015年2月~2016年6月在我院进行诊治的乳腺癌患者150例,应用高频二维超声结合彩色多普勒血流显像技术,观察腋窝肿大淋巴结的声像图及血流情况。结果:经二维超声发现,乳腺癌腋窝良性淋巴结的皮质多向心增厚(68.93%)、长短径比L/S多>2.0(70.58%)、多不融合(93.14%)、多无钙化斑(97.06%);腋窝转移性淋巴结的皮质多偏心增厚(68.48%)、长短径比L/S多<2.0(69.57%)、多融合(68.48%)、多有钙化斑(77.17%);两者相比有明显差异(P<0.05);经彩色多普勒血流显像技术发现,乳腺癌腋窝良性淋巴结的血流信号分布多呈门型(63.17%),血流丰富程度多为Ⅱ级(54.35%);腋窝转移性淋巴结的血流信号分布多呈周边型(68.93%),血流丰富程度多为Ⅲ级(72.83%);两者相比有明显差异(P<0.05)。结论:乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结在内部回声、形态、血流分布特点等方面有显著的差异,高频彩色多普勒超声对乳腺癌腋窝良性淋巴结与腋窝转移性淋巴结具有较高的鉴别价值。
Objective: To study the value of high-frequency color Doppler ultrasound in differentiating axillary lymph nodes from axillary lymph nodes in breast cancer. Methods: 150 breast cancer patients who were treated in our hospital from February 2015 to June 2016 were enrolled in the study. Ultrasonography combined with color Doppler flow imaging was used to observe the sonography of axillary lymph nodes And blood flow. Results: Two-dimensional ultrasonography showed that axillary lymph nodes in breast cancer were hypercortical (68.93%) with L / S more than 2.0 (70.58%), no more polyphasia (93.14%), (97.06%). The extracranial cortex of armpit metastatic lymph node was 68.48%, the L / S ratio was less than 2.0 (69.57%), multiple fusion (68.48% (P <0.05). The results of color Doppler flow imaging showed that the distribution of blood flow in benign axillary lymph nodes of breast cancer was mostly portal (63.17%), and the degree of blood flow was more (54.35%). The distribution of axillary metastatic lymph nodes was mainly peripheral type (68.93%), and the degree of blood flow was grade Ⅲ (72.83%). There was significant difference between the two groups (P <0.05) ). Conclusion: Breast cancer axillary lymph nodes and axillary lymph nodes in the internal echo, morphology, distribution characteristics of blood flow and other significant differences, high-frequency color Doppler ultrasound breast cancer axillary lymph nodes and axillary lymph nodes have a higher The identification value.
