Figure 1 Images of various advanced imaging modalities in Barrett’s oesophagus. A: Acetic acid used to visualise Barrett’s oesophagus, ridge pattern signifying Intestinal metaplasia; B: High magnification white light endoscopy-round pits in keeping with columnar mucosa without intestinal metaplasia; C: Corresponding area on image B seen with narrow band imaging (NBI) and magnification; D: High magnification white light endoscopy - absent pits in keeping with columnar mucosa with intestinal metaplasia; E: Corresponding area on image D seen with NBI and magnification; F: High magnification white light endoscopy - villous/ridge pits in keeping with columnar mucosa with intestinal metaplasia; G: Corresponding area on image F seen with NBI and magnification; H: White light endoscopy of Barrett’s cancer; I: Corresponding area on autoflourescence imaging; J: Abnormal area on NBI with magnification showing total distortion of the pit pattern.
