Narrow Band Imaging (NBI) is an endoscopic method which allows observation of mucosal changes characteristic for development and
growth of epithelial tumours. A higher contrast between the mucosal epithelium and blood vessels is achieved using filtered light comparing
to white light observations. This allows detection of small mucosal changes, few millimetres in diameter, which are not observable
using white light. In otorhinolaryngology the method is used in flexible and rigid endoscopic investigation in an outpatient procedure,
as well as during surgical procedures. It is used as a screening method, in the follow-up of patients with a history of cancer treatment,
and also to perform targeted biopsy and for determination of resection margins in cancer surgery.
