1 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 (December 2005) DOI: /j.athoracsur Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

2 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.

3 Fig 2 Shown is the inflated balloon around a radial endobronchial ultrasound probe. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

4 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.

5 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  , DOI: ( /j.athoracsur ) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

6 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.
