Narrow Band Imaging™ Technology
Olympus developed narrow band imaging technology to enhance observation of mucosal tissue. Now with the EVIS EXERA III™ system, an improved version gives twice the viewable distance and is significantly brighter.1
NBI™ Technology is an optical imaging technology that enhances the visibility of vessels and other tissue on the mucosal surface. NBI technology works by filtering the white light into specific light wavelengths that are absorbed by hemoglobin and penetrate only the surface of human tissue. As a result, with Narrow Band Imaging, capillaries on the mucosal surface are displayed in brown and veins in the submucosa are displayed in cyan on the monitor.1
Olympus Narrow Band Imaging Technology has FDA cleared claims for use in both upper GI and Lower GI and is recognized as an important technology by the ASGE as for:
Adopting real-time imaging–assisted endoscopic targeted biopsy during endoscopic surveillance of Barrett’s esophagus and adopting real-time endoscopic assessment of the histology of diminutive colorectal polyp.1
Upper GI Benefits
See Before You Sample – High-definition Narrow Band Imaging targets suspicious areas to biopsy for Barrett’s Esophagus.1
Lower GI Benefits
Suspect Before You Resect – High-definition Narrow Band Imaging can be used to assess the histology of diminutive colorectal polyps.1Suspect before you resect.
Olympus’ High-Definition Narrow Band Imaging (HD NBI) technology has enhanced visual observation of mucosal and vascular patterns for years. Now you can use HD NBI technology with 190 series colonoscopes to assess the histology of diminutive colorectal polys.
Narrow Band Imaging assists an experienced endoscopist employing a validated polyp classification system such as the NBI International Colorectal Endoscopic (NICE) classification with high confidence, in distinguishing diminutive adenomatous polyps from non-adenomatous polyps during colonoscopy.1
Experienced endoscopists using Narrow Band Imaging technology demonstrated 93% sensitivity (89-96%, 95% Confidence Interval, 59-98% range) in predicting adenomatous histology of diminutive polyps during colonoscopy when made with high confidence.1
Endoscopists using Narrow Band Imaging technology demonstrated 85% specificity (74-92%, 95% Confidence Interval, 44-99% range) in predicting adenomatous histology of diminutive polyps during colonoscopy when made with high confidence.1
Experienced endoscopists using Narrow Band Imaging technology demonstrated >90% Negative Predictive Value in predicting adenomatous histology of diminutive polyps during colonoscopy when made with high confidence.1
In a randomized clinical trial, endoscopists using near focus mode colonoscopes with NBI technology were more likely to make high confidence predictions of diminutive polyp histology than those using standard focus colonoscopies.1
Narrow Band Imaging-assisted endoscopists have achieved >90% agreement with pathological analysis in assigning post-polypectomy patient surveillance intervals following colonoscopy1
Narrow Band Imaging technology has met the American Society for Gastrointestinal Endoscopy (ASGE) Preservation and Incorporation of Valuable Endoscopic Innovations (PIVI) thresholds for real-time assessment of diminutive colorectal polyps by expert endoscopists when optical biopsy assessment was made with high confidence.1
Don't leave biopsy to chance.
Olympus’ High-Definition Narrow Band Imaging (HD NBI) technology has enhanced visual observation of mucosal and vascular patterns for five years. Now you can use HD NBI technology to target suspicious areas in Barrett’s esophagus patients for biopsy. The ability to take fewer biopsies saves valuable time, while providing the same great level of patient care.1
Better Interpretation Tool
HD NBI technology provides contrast, which may aid in the interpretation of mucosal morphology, vascular patterns, and blood vessel appearance in patients with Barrett’s esophagus.1
Less Time
HD NBI technology facilitates targeted biopsies in patients with Barrett’s esophagus, which can save valuable procedure time.1
Fewer Biopsies
