Trial Information

The Diagnostic Yield of Narrow Band Imaging Videobronchoscopy in Lung Cancer


Inspection with high resolution endoscopy was followed by NBI. Detected lesions were
biopsied. applied the system of shibuya et al. to analyze and classify vascular patterns by
NBI into four categories (spiral and screw pattern, dotted pattern, tortuous pattern,
avascular pattern) compared with the known diagnostic yield of conventional white light
bronchoscopy, An equivalent or superior result will also significantly impact on patient
care This technology could aid not only early-stage lung cancer diagnosis but also more
accurate local staging of lung cancer.
