BACKGROUND AND STUDY AIMS Magnifying endoscopy with narrow-band imaging (ME-NBI) is more reliable than chromoendoscopy (CE) for delineating the horizontal extent of early gastric cancers prior to endoscopic submucosal dissection (ESD). However, the added benefits of ME-NBI over CE in terms of the difference in magnification level have yet to be elucidated. The aim of this study was to investiga...

BACKGROUND/AIMS Advanced endoscopic imaging technologies have been used for the early detection and differentiation of colonic cancers recently. We aim to evaluate the diagnostic efficacy of autofluorescence imaging (AFI), narrow-band imaging (NBI), and AFI combined with NBI for colonic cancers. MATERIALS AND METHODS We searched Medline/PubMed, Embase, Web of Science, and Cochrane Library dat...

conclusions nbi cystoscopy improved the detection rate. although false positives were more common with nbi, this was not statistically significant. nbi found additional aggressive tumors, which underscores the impact of detection in eortc recurrence risk scoring. results fifty patients, aged 63.86 ± 10.05 years, were enrolled. the overall detection rate was 98.9% for nbi vs. 89.4% for wli (p = ...

Narrow band imaging (NBI) is a new endoscopic technique in which images of mucosal microstructures and capillary structures are enhanced by shifting the light spectrum to a narrow band. Image-enhanced gastrointestinal endoscopy using NBI has improved the qualitative diagnosis of the grade and depth of invasion of an atypical lesion. NBI is current...

(n = 150) Nonbattle injury (NBI) continues to be a leading cause of morbidity among troops currently deployed to Iraq and Afghanistan. To assess NBI incidence, impact, and risk factors, a survey was given to soldiers during mid- or postdeployment from Iraq, Afghanistan, and surrounding region, from January 2005 through May 2006. Among 3,367 troops completing a survey, 19.5% reported at least on...

Narrow band imaging (NBI) has been used in the gastrointestinal endoscopy field as a novel endoscopic imaging technique and has contributed to improved qualitative diagnosis and detection of lesions. However, there are only a few studies of use of NBI in the gynecology field. We applied NBI in flexible hysteroscopy at our outpatient clinic and evaluated the utility of NBI hysteroscopy for diagn...
