目的：研究内镜窄带成像技术在早期食管癌及其癌前病变的运用价值。
Objective:To study the value of the endoscopic narrow band imaging technique in distinguish the early esophageal cancer and premalignant lesions .
探讨内镜窄带成像技术(NBI)在食管癌及癌前病变诊断中的价值。
To assess the value of narrow-band imaging (NBI) in diagnosis of early cancer and premalignant lesions in esophagus.
窄带成像技术将结肠镜常规发射的白光改变为蓝光，以此提供一个较窄的波长，加强结肠表面结构的视觉对比度。
NBI changes the white light normally emitted by the colonoscope to a bluish light, providing a narrower wavelength and enhancing visual contrast of the surface structure of the colon.
