Advanced imaging technologies are enabling targeted biopsies or endoscopic resections due to better visualization of the mucosal architecture. This new concept of 'smart biopsies' is in particular important for patients with higher risk for development cancer (e.g. ulcerative colitis) but can also be beneficial for screening purposes. This short review will focus on new imaging modalities like chromoendoscopy, digital chromoendoscopy, high-definition endoscopy and confocal laser endomicroscopy in the lower GI tract which will be crucial in the future to detect colorectal neoplasia earlier then before.
先进的成像技术能够更好地观察黏膜结构，从而实现靶向活检或内镜下切除。这种“智能活检”的新概念对于有更高癌症发病风险的患者（如溃疡性结肠炎）尤其重要，但也有益于筛查目的。这篇简短的综述将重点介绍下消化道中的新型成像方式，如染色内镜、数码染色内镜、高清内镜和共聚焦激光内镜，这些技术在未来对于更早地发现结直肠肿瘤至关重要。
