 NBI(narrow band imaging)is a technique that modifies endoscopic observational spectroscopy to a narrow band range(shift to shorter wavelength), which permits enhancement of lesions and allows visualization of the fine structure of the mucosal surface or microvessels. NBI is useful for colonoscopic screening examination as it has a higher lesion detection rate than traditional methods ; however, further studies are required because contrary results have also been reported. NBI can distinguish between neoplasia and non-neoplasia(optical/digital chromoendoscopy without the use of dyes). In addition, this method showed superior ability to discriminate between colonic cancer and adenoma(Further studies are required for determination of the depth of the lesions). Further investigations are required to verify the correlation with classification for capillaries(structures)and validation study, inter-and intraobserver variability, and learning curve should be examined in future.
