1 Figure 2 Endoscopic imaging of intestinal villi
Figure 2 | Endoscopic imaging of intestinal villi. a | Image illustrating the improved villous contrast provided by optimal band imaging (OBI) and high definition (HD) endoscopy. b | An equivalent image utilizing HD endoscopy alone. c | Narrow band imaging (NBI) of regions of tissue exhibiting healthy villi. d | NBI images showing regions of tissue with absent villi. e | HD endoscopy image recorded in an adult with EED exhibiting partial blunting of villi. f | HD endoscopy image in an adult with EED showing subtotal villous atrophy.
