Background and study aims: Narrow band imaging (NBI) has been developed as a new technique to differentiate tissue patterns in vivo. The aim of this prospective study was to evaluate the diagnostic value of NBI endoscopy with and without high magnification in the differentiation of neoplastic from non-neoplastic colorectal polyps. Patients and methods: Among 200 colorectal polyps from 131 patients, 100 lesions were classified according to vascular patterns by NBI endoscopy with optical magnification and 100 lesions without high magnification. Additionally, the clarity of the vessel network was determined. Histol…
