| [ Summary ] | Narrow band imaging (NBI) development coincided with that of endoscopic spectroscopy. As part of the "New 10‒year Strategy to Overcome Cancer," quantitative colorimetry (spectrometry) of the gastrointestinal mucosa was performed for diagnosis during the second half of the 1990s. In 1999, an experiment was conducted to confirm the NBI concept by using a multispectral camera capable of capturing spectroscopic images with a high radiant flux light source. The experiment showed that using a narrow band of light with a central wavelength of 415 nm improves the contrast of capillary imaging that is otherwise difficult to discern using white light ; this marked the beginning of NBI endoscopy system development. Subsequently, an intensive effort by endoscopists in Japan and overseas confirmed the clinical usefulness of NBI. In 2006, Olympus finally announced the next generation NBI endoscopy system, the EVIS LUCERA SPECTRUM. NBI enables physicians to observe microvascular and microsurface patterns on lesion surfaces, and is currently used for the diagnosis of lesions in various organs including the digestive organs. |
