Bronchoscopy is the visual inspection of the trachea and airways using a rigid or flexible scope through the nose or mouth, while the patient is under anesthesia. 3D Virtual bronchoscopy examines the airways using data obtained from a multislice CT of the neck and upper chest, targeted to the airway, with a single breath hold. No anesthesia, No pain. The images to the right are from such an exam with the viewer proceeding from the trachea into the left mainstem bronchus, and finally into the left lower lobe bronchus.
