Hepatol. doi:10.1038/nrgastro.2017.147 Figure 4 Tethered capsule OCT and OCT-based visualisation of intestinal villi Figure 4 | Tethered capsule OCT and OCT-based visualisation of intestinal villi. a | A tethered capsule optical coherence tomography (OCT) system. PP, polypropylene ball handle. b | 3D view of the entire oesophagus in a patient with Barrett oesophagus, obtained via 3D rendering of data collected as the OCT capsule is withdrawn from the stomach. Distinct features are revealed by OCT including normal gastric mucosa (left cross-sectional image), high-grade dysplasia (HGD) and intramucosal carcinoma (IMC) (centre), and normal squamous mucosa (right). c | Probe-based OCT image collected in the duodenum (left) and corresponding histological image (right) indicating visualisation of the villous structure in healthy tissue. Finger-like villi are clearly resolved (arrows). d | Probe-based OCT image (left) showing areas of villous atrophy (arrows) exhibiting a flattened mucosal surface, and the corresponding histological image (right).
