Figure 1 (A) High-resolution white-light endoscopy, (B) AFI, and (C) NBI. On AFI, adenomas become purple and normal colonic mucosa appears green; on NBI a Kudo pit pattern type IIIL is seen.

Figure 2 (A) Green color, (B) ambiguous color, and (C) purple color during AFI. Green color corresponds to nonneoplastic histology, purple color corresponds to adenomatous tissue, and ambiguous-colored lesions can be associated with both nonneoplastic and adenomatous polyps.
