In the past few years, newly developed procedures and technologies have improved endoscopic recognition of the gastrointestinal tract. In particular, narrow band imaging, multiband imaging, and contrast enhancement make possible the "real-time," on demand recognition of the gastrointestinal mucosa during the endoscopic examination. These imaging techniques have been designed to enhance visualization of the vascular network and surface texture of the mucosa in an effort to improve tissue characterization, differentiation, and diagnosis. These techniques are considered as potential alternatives to chromoendoscopy because they provide contrast enhancement of tissue surface structures. This review focuses on data published on multiband imaging system. We report the technological basis of the system and speculate on its applications. Therefore, PubMed was searched for articles published up to 31 October 2009 using, in combination, these terms: "multiband imaging," "band imaging," "endoscopy," "high-resolution," "gastrointestinal," "FICE," "magnification," "spectral endoscopic images," "computed virtual chromoendoscopy." The reference list of articles identified in the initial PubMed search was reviewed for further relevant publications. Abstracts of communications presented to the most relevant international meetings and congresses were also included in this review. We did not carry out meta-analyses and reviewed only articles published in English.
