NARROW BAND IMAGING-INSIGHT INTO THE INTERIORS

Abstract

Narrow Band Imaging (NBI) is a recent method of imaging which can be used as an adjunctive diagnostic device along with standard diagnostic protocol. This technology will improve clinicians' ability to detect early changes in inflammatory and dysplastic tissues. Recently there has been a rapid progression in its use in patients with head and neck cancer. NBI system is based on the principle of producing blue light which penetrates less deeply into the tissues of precancerous and cancerous lesions when compared to that of conventional white light and thus helps clinicians' to get a much better view of superficial structures.
