Abstract

Abstract:

Magnifying endoscopy with narrow-banding imaging(ME-NBI)is a new technique.Here we introduce several NBI-types of colorectal lesions and some clinical trials about ME-NBI.Compared with other endoscopic technique, ME-NBI has broad prospects in the diagnosis of early stage colorectal cancer.

Key words: Amplifiers, Early diagnosis, Colorectal neoplasms, Narrow-banding imaging
