Book excerpt: Endobronchial ultrasonography (EBUS) is an exciting new diagnostic tool that has added significantly to the diagnosis and staging of lung cancer and other thoracic diseases. This book is co-authored by one of the technology's pioneers and will help the reader to use EBUS to diagnose and stage lung cancer and a variety of different tumours of the chest region. Endobronchial Ultrasonography covers all of the standard techniques and the new developments involved in EBUS as it combines two common procedures, bronchoscopy and real-time ultrasonography. This allows physicians to obtain precise biopsies of lymph nodes and masses within the chest cavity. Over 250 high quality colour digital images are featured throughout the book to illustrate the different applications of EBUS, complemented by specific case studies. This book is accompanied by a companion website featuring over 30 video clips cited in the text.
