Chromoendoscopy pertains to image-enhanced endoscopic techniques such as dye-based chromoendoscopy and electronic chromoendoscopy using narrow-band imaging, flexible spectral imaging color enhancement, and i-scan. Dye-based chromoendoscopy has been demonstrated to improve colorectal dysplasia detection in high-risk patients with long-term inflammatory bowel disease, and electronic chromoendoscopy techniques have been shown to improve characterization of diminutive colorectal lesions, allowing for optical diagnosis during a colonoscopy examination. This article reviews endoscopic imaging using chromoendoscopy techniques for colorectal dysplasia evaluation.
色素内镜检查属于图像增强内镜技术，如基于染料的色素内镜检查以及使用窄带成像、灵活光谱成像颜色增强和i-scan的电子色素内镜检查。基于染料的色素内镜检查已被证明可提高长期炎症性肠病高危患者结直肠发育异常的检测率，电子色素内镜检查技术已被证明可改善微小结直肠病变的特征描述，从而在结肠镜检查期间进行光学诊断。本文综述了使用色素内镜检查技术进行结直肠发育异常评估的内镜成像。
