How Does Narrow Band Imaging (NBI) Work?
Olympus Narrow Band Imaging (NBI) is an optical technology available for a variety of medical disciplines which helps to visualize the minutest vascular and mucosal patterns. NBI uses only wave lengths absorbed by hemoglobin for maximum contrast.
A number of studies highlight the clinical value of NBI, especially with regard to the detection of cancer and characterization of suspicious mucosal areas.
Compared to white-light endoscopy, the images of capillaries are less blurred and the probability of missing a lesion is reduced.
NBI for ENT in a Nutshell
● Exclusive optical technology built in all the recent Olympus imaging systems.
● NBI is currently the only technology that works with Full-HD and Ultra-High Definition systems
● NBI can be used in the office with flexible scopes as well as in the operating room with rigid scopes.
NBI Optimizes Clinical Outcomes in ENT
Numerous studies, including a growing number of RCTs and meta-analyzses, highlight the clinical value of NBI, especially with regard to the detection of cancer and thorough examination of suspicious mucosal areas. By providing high image quality and contrast in Full- HD or Ultra High Definition, NBI may reduce the surgical margin and also the number of biopsies.

NBI comes with Olympus Medical equipment at no additional costs for extra equipment, disposables or drugs. It is a key function of Olympus endoscopy system, and has shown to provide clinical quality, efficiency gain and cost saving in other indications.
