Results: Using the Kudo classification of mucosal patterns, NBI with magnification resulted in
a sensitivity of 90.5% and a specificity of 89.2% for the differentiation of neoplastic vs. non-
neoplastic lesions. This performance was comparable to magnifying chromoendoscopy with
a sensitivity of 91.7% and a specificity of 90%, respectively. Using vascular patterns for
differentiation, NBI with magnification correctly identified 93.7% of neoplastic polyps and
89.2% of non-neoplastic colorectal lesions, whereas magnifying chromoendoscopy had a …
