蓝激光成像在上消化道早癌诊断中的应用进展

Advances in Application of Blue Laser Imaging in Diagnosis of Early Upper Gastrointestinal Cancer

蓝激光成像(BLI)是一种可发射两种不同波长激光束的新型内镜系统,通过明亮、高分辨率的图像观察食管和胃黏膜浅层微血管和黏膜表面微结构,从而有助于上消化道早癌的诊断,与现有内镜技术相比有其独特优势。本文就BLI在上消化道早癌诊断中的应用进展作一综述。

Blue laser imaging（ BLI） is a new endoscopic system equipped with the laser beam emitting two different wavelengths. It produces bright and high resolution images for observation of microvascular and microsurface patterns of esophageal and gastric mucosa,helping the diagnosis of early upper gastrointestinal cancer. Compared with the existed endoscopic techniques,BLI shows its unique advantages. In this article,advances in application of BLI in diagnosis of early upper gastrointestinal cancer were reviewed.
