Narrow-band imaging with magnifying endoscopy for the evaluation of gastrointestinal lesions

Figure 7 Assessment of colonic lesions by narrow band imaging with magnification endoscopy according to different classification systems. A: Hyperplastic polyp: absent mesh brown capillary network (Type I MBCN) (Sano classification); a lighter color of the polyp than the background, isolated vessels coursing across the lesion (NICE criteria); B: Adenomatous polyp: regular mesh brown capillary network (Type II MBCN) and Kudo’s Type IV mucosal pattern; the brown color relative to background, thick brown vessels surrounding white structures (NICE criteria); C: Cancerous colonic lesion: irregular mucosal and vascular patterns (Type III MBCN); D: Deep submucosal invasive colorectal cancer: amorphous surface pattern and disrupted vessels (NICE criteria).
