PURPOSE: To evaluate the value of OCT in identifying small airway lesions in patients with COPD.

METHODS: A total of 130 patients undergoing bronchoscopy owing to pulmonary opacity or infection were recruited. According to their medical history, PFT and chest CT, these patients were divided into the normo-PFT non-smoking group, normo-PFT smoking group or the COPD group. In the three groups, 0.9mm OCT imaging catheters were advanced into third- to ninth-generation sub-segmental bronchi of the both lower lungs (B8 and B9) through an ultrathin bronchoscope under guidance of virtual bronchoscopic navigation (VBN) for continuous OCT scan. Image-based measurement was used to compare the size of lumen, wall thickness and wall structure of these bronchi among the three groups.
