Abstract
BACKGROUND: Narrow-band imaging (NBI) and autofluorescence imaging (AFI) are new bronchoscopy technologies that are important in lung cancer diagnosis. The aim of this study is to determine whether or not the combination of these two technologies can improve sensitivity and specificity of lung cancer diagnosis.Entities:

1三种不同光谱下癌变支气管粘膜的显影。A:WLB显示左肺下叶间嵴水肿、肥厚;B:AFI显示间嵴品红色改变;C:NBI显示间嵴粘膜肥厚、隆起,表面血管异常,表现为“芝麻点”样改变。
Image of WLB, AFI and NBI. A: Irregularmucosa are identified at the bifurcation of the left lower lobe bronchi by WLB; B: The AFI image clearly is magenta at the abnormal area; C: In the NBI mode, atypical dotted vessels are visible. The biopsy showed squamous cell cancer.
