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 visualise the tiniest vascular and mucosal patterns. NBI uses only wavelengths absorbed by haemoglobin for maximum contrast.

A number of studies highlight the clinical value of NBI, especially with regard to the detection of cancer and characterisation 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 (see Olympus 4K system).
  • NBI can be used in the office with flexible scopes as well as in the operating theatre with rigid scopes.

NBI Optimises clinical outcomes in ENT

Clinical value

Numerous studies, including a growing number of RCTs and meta-analyses, highlight the clinical value of NBI, especially regarding the detection of cancer and the 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.

Cost-effectiveness

NBI offers superior efficacy compared to white-light endoscopy in the early diagnosis of laryngeal cancer in pre, intra and post-operative stages. As tumours can be detected at an early stage using NBI technology, complications and the time that a patient spends at a hospital can be reduced. Early diagnosis and treatment is thought to result in a reduction in future treatments and recurrence of the disease.

NBI comes with Olympus Medical equipment at no additional cost for extra equipment, disposables or drugs. It is a key function of the Olympus endoscopy system, and has been shown to provide clinical quality, efficiency gain and cost savings in other indications.[4,5]

High versatility and easy handling

NBI is suitable for numerous ENT endoscopy procedures, such as laryngoscopy, larynx, oral cavity, and sinus surgery as well as in otology. NBI is part of all Olympus imaging systems, such as VISERA ELITE II. It can be used with flexible and rigid scopes and is available at the push of a button, allowing for convenient usage with no extra manual configuration before the procedure.
