Endoscopic Optical Coherence Tomography (OCT): Advances in Gastrointestinal Imaging
Figure 2
Barrett’s esophagus (BE) without dysplasia. (a) Cross-sectional OCT imaging showing clear differences in layered architecture between gastric (GA), normal squamous (NS), and BE regions. BE regions exhibit distortion of the layered architecture and abnormal glandular features. (b) Cross-sectional OCT images around GEJ. BE glands (red arrows) are clearly observed (EP: epithelium; MM: muscularis mucosae in photos A–C).
