Abstract

The result of the clinical trial using the lung imaging fluorescence endoscope (LIFE) was reported. A total of 77 biopsy confirmed sites from 30 patients were evaluated. The sensitivity for metaplasia detection by the LIFE system was 96% compared to 28% by conventional bronchoscopy. The LIFE system was found to be useful in detecting subtle cancerous/precancerous lesions.
