About

Narrow band imaging (NBI) videobronchoscopy is an optical technique in which filtered light enhances superficial neoplasm based on their neoangiogenic pattern. The objectives of this study investigate its better diagnostic yield in the assessment of lung cancer than conventional flexible bronchoscopy.

Full description

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.
