Endobronchial elastography is a novel imaging technology which visualizes the relative stiffness of the targeted tissue. Endobronchial elastography can be used for differentiating malignant and benign lymph nodes during nodal staging in patients with lung cancer. Another possible utility of endobronchial elastography would be targeting high-risk area within the intrathoracic lymph node. During nodal staging using endosonographic technology, a false negative result was known as a limitation of needle biopsy modality that could be caused by the micrometastasis within the lymph node. We report the identification of mediastinal lymph node metastasis in a patient with squamous cell carcinoma by visualization of the metastatic site using endobronchial elastography.
经支气管内弹性成像技术是一种新型的成像技术，可使目标组织的相对硬度可视化。经支气管内弹性成像可用于在肺癌患者的淋巴结分期中区分恶性和良性淋巴结。经支气管内弹性成像的另一个可能的用途是针对胸内淋巴结内的高危区域。在使用超声内镜技术进行淋巴结分期时，已知假阴性结果是针吸活检方式的一个局限性，这可能是由于淋巴结内的微转移所致。我们报告了一例通过经支气管内弹性成像显示转移部位来识别鳞状细胞癌患者纵隔淋巴结转移的病例。
