摘要

2012年富士胶片公司开发了一款激光内镜系统。该系统使用窄带光技术BLI、BLI-bright和LCI。据报道，这些技术对肿瘤检测和鉴定是有用的。此外，2016年至2017年在美国和欧洲等一些尚未批准使用激光内镜系统的地区发布了使用四个LED多光源整合技术的新型内镜系统。该系统使用LED代替激光光源实现BLI和LCI。多份报告表明这些技术提高肿瘤检出率。在本文中，我们回顾了激光和LED内镜系统的BLI和LCI在肿瘤检测和鉴定中的有效性。

Abstract: A laser endoscopy system was developed in 2012. The system allows blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) to be performed as modes of narrow-band light observation; these modes have been reported to be useful for tumor detection and characterization. Furthermore, an innovative endoscopy system using four-light emitting diode (LED) multilight technology was released in 2016 to 2017 in some areas in which laser endoscopes have not been approved for use, including the United States and Europe. This system enables blue light imaging (this is also known as BLI) and LCI with an LED light source instead of a laser light source. Several reports have shown that these modes have improved tumor detection. In this paper, we review the efficacy of BLI and LCI with laser and LED endoscopes in tumor detection and characterization.
