Narrow Band Imaging (NBI)

  • – NBI is an optical image technology that enhances structural mucosal pattern (pit pattern) as well as mucosal/submucosal vessels by employing the characteristics of the light spectrum
  • – It enhances the visibility of blood vessels and other tissue on the mucosal surface
  • – It works by filtering the white light into specific light wave lengths that are absorbed by hemoglobin and penetrate only the surface of human tissue
  • – As a result, with NBI, capillaries on the mucosal surface are displayed in brown and veins in the submucosa are displayed as cyan (নীল-সবুজ) on the monitor
  • – NBI is not intended to replace histopathological sampling as a means of diagnosis
  • – A special filter is electrically activated by a switch in the endoscope leading to the use of blue (415nm wave length) and green (549 nm wave length) light. The peak light absorption of hemoglobin occur at these wave length
