Narrow Band Imaging (NBI)
NBI provides great potential for defining the nature of a bronchial lesion, allowing a closer, more accurate look at the angiogenic process. NBI is a promising technology as it combines good sensitivity with improved specificity. It allows superior discrimination between low- and high-risk lesions (such as CIS and severe dysplasia). NBI is available with standard videoscopes on recent Olympus video endoscopy platforms.
