Standard Techniques of Imaging of IASLC Borders by Endoscopic Ultrasound.

Linear endoscopic ultrasound is useful in the diagnosis and staging of non-small cell lung cancer. Endoscopic ultrasound has been proposed as the first test to be used, before bronchoscopy, for staging of lung cancer. The International Association for the Study of Lung Cancer has redefined the anatomic borders of lymph node stations. We describe the techniques of linear endoscopic ultrasound for mapping of the lymph nodes as defined by the International Association for the Study of Lung Cancer classification.
