Conventional imaging procedures proved to be insufficient for staging of lung cancer, especially with respect to N-stage, infiltration of mediastinal structures, and early lung cancer. As also the view of the endoscopist is restricted, we developed the new method of endobronchial ultrasonography (EBUS) as an adjunct to conventional bronchoscopy. The initial technical problems were solved by development of a balloon catheter for application of miniaturized 20-MHz probes.
