OSPINA NIETO, John  e  VILLAMIZAR SUAREZ, John. Usefulness of the narrow band image (N.B.I) in the diagnostic endoscopy. Rev Col Gastroenterol [online]. 2009, vol.24, n.1, pp. 60-70. ISSN 0120-9957.

The NBI (Narrow Band Imaging) or image of narrow band is a tool of endoscopic visualization developed in Japan in the National Cancer Center for the Drs. Gono K. and Sano Y. in the year 2001. This "digital Chromoendoscopy" linked to the systems of magnification endoscope allows a more detailed evaluation of the mucous surface and of its vascular net, facilitating hereby the diagnosis and follow-up of early injuries of the gastrointestinal tract, as well as of pathologies as Barrett’s oesophagus, the cancer, the polyps and the inflammatory intestinal disease, among others. In this article we expose a review of the optical principles of the NBI and of the utility of the same one in the routine diagnoses and therapeutic endoscopy and the experience with the same one in our institution (Cardiovascular Hospital of the child of Cundinamarca).
