Validation of Fujinon intelligent chromoendoscopy with high definition endoscopes in colonoscopy

Figure 1 Presentation of a sequence of images for the different diagnostic modalities corresponding to a case included in study two (histopathological diagnosis: tubular adenoma with mild dysplasia). A: Circumscribed erythema with loss of vascular pattern, which can be difficult to detect; B: Observation with Fujinon intelligent chromoendoscopy (FICE) 4. Note that the innominate grooves can be seen in the normal surrounding mucosa; C: Observation under 0.5% indigo carmine (IC), which reveals a 0-IIc depressed lesion 3 mm in size; D: High magnification view, showing vascular pattern type Sano II; E: Same magnification image observed under FICE 4, which provides enhanced vascular contrast; F: Under 0.5% IC plus magnification, the depression and the vascular patterns are evident.
