Endobronchial ultrasonography is an imaging method which has been developed during the last decade. It can be performed by applying tools that are used today during conventional bronchofiberscopy. This method is recommended for identifying processes that affect the bronchial wall and the mediastinal lesions next to central airways as well as for localizing peripheral lung lesions. The authors present a compilation of publications and summarize their own experiences based on 44 cases of application of this method.
