Diagnosis of Minute Gastric Cancer by Narrow Band Imaging

  • Junko Fujisaki


Narrow band imaging (NBI) is a new electronic endoscopy system ideally suited to the observation of surface structures, including capillaries. With NBI, shortwavelength light radiated through a narrow band filter is strongly absorbed by hemoglobin, thereby allowing surface vascular structures to be distinctly visualized (1).
