研究目的:

本研究是一项多中心、随机对照试验,旨在评估人工智能(AI)系统在结肠镜检查中,与标准高清结肠镜相比,是否能协助内镜医师提高结直肠腺瘤和癌症的检出率。由于目前的结肠镜检查存在局限性(包括漏诊风险),本试验旨在确定AI是否能提升筛查质量和诊断准确性。  

Objectives of Study:

This study is a multi-center, randomized controlled trial designed to evaluate whether an artificial intelligence (AI) system can assist endoscopists to improve the detection rate of colorectal adenomas and cancers during colonoscopy compared to standard colonoscopy. Early screening and diagnosis are key to reducing the burden of colorectal cancer, but current colonoscopy has limitations, including the risk of missed lesions. This trial aims to determine if AI can enhance screening quality and diagnostic accuracy.
