摘要
超声技术作为术前评估乳腺癌腋下淋巴结转移(axillary lymph node metastasis,ALNM)状态最常用的方法,可通过二维灰阶图像、血流表现、弹性成像、超声造影等手段根据淋巴结的形态、纵横比、皮质状态、淋巴门表现、血流情况等指标预测淋巴结转移与否。但超声技术受众多影响因素如腋下淋巴结的大小、位置、腋窝深度、医师经验、超声仪器分辨率不同等的限制,其检出率及准确率仍未达到令人满意的水平。因此,如何提高超声对乳腺癌ALNM的评估效能成为亟需解决的问题。
Ultrasonography is the most commonly used method to evaluate the status of axillary lymph node metastasis （ALNM） in breast cancer. It can be used to predict axillary lymph node status by conventional two-dimensional gray-scale, blood flow, elastography and contrast-enhanced ultrasound according to the morphology, long- to- short axis ratio, cortical thickening, hilum status, blood flow and other indicators. However, the positive rate and accuracy of ultrasonographic techniques are not satisfactory due to many factors including the size and position of axillary lymph nodes, axillary depth, experience of physicians and different resolution of ultrasonographic instrument. Therefore, how to improve the efficacy of the evaluation of axillary lymph node metastasis in breast cancer has become an urgent problem.
