Autofluorescence Bronchoscopy and Endobronchial Ultrasound: A Practical Review David Feller-Kopman, MD, William Lunn, MD, Armin Ernst, MD The Annals of Thoracic Surgery Volume 80, Issue 6, Pages 2395-2401 (December 2005) DOI: 10.1016/j.athoracsur.2005.04.084 Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions
Fig 1 The conventional bronchoscopic image (left) shows a fairly normal right upper lobe uptake in a patient with sputum cytology positive for non-small cancer and a negative chest computed tomography. The right panel shows the same area with autofluorescence endoscopy. The purplish discoloration is abnormal and biopsy revealed carcinoma in situ.

Fig 2 Shown is the inflated balloon around a radial endobronchial ultrasound probe. The Annals of Thoracic Surgery 2005 80, 2395-2401DOI: (10.1016/j.athoracsur.2005.04.084) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions
Fig 3 Image of a bronchoscope with an incorporated radial ultrasound in the tip. This allows for real time imaging of a biopsy needle exiting from a side channel, similar to existing endoscopic ultrasound technology.

Fig 4 Image of a lymph node biopsy under endobronchial ultrasound guidance. The needle (arrows) is clearly visible in the lymph node. The Annals of Thoracic Surgery 2005 80, 2395-2401DOI: (10.1016/j.athoracsur.2005.04.084) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions
Fig 5 (A) Image on the left shows a normal endobronchial ultrasound image of the left mainstem bronchus branching into the left lower lobe (LLL). Visible structures are the left lower pulmonary vein (LLPV), a lymph node (LN), and the left atrium (LA). (B) Image shows an abnormal endobronchial ultrasound image of a tumor invading the wall and extending through the cartilage layer. Endobronchial curative treatment would not be promising in this patient.
