摘要 膀胱镜及细胞学检查是目前检测和随访非肌层浸润性膀胱肿瘤的主要方法。然而,这些检查存在检出率低、不能提供组织病理学信息、不利于确定肿瘤分期等局限。目前,一些新的光学成像技术已经出现,如窄谱成像、拉曼光谱和光学相干断层扫描等。其中窄谱成像技术允许在不加入光敏剂的情况下增强黏膜下层表浅血管和毛细血管的可视性,应用于膀胱镜检时可明显提高膀胱肿瘤的检出率。拉曼光谱可以同时定性和定量分析组织的分子成分,从而实时、客观地预测病变组织的病理类型,并有望在尿液样本早期检测膀胱肿瘤方面得到应用。光学相干断层扫描可提供对组织实时、高清晰度的断层扫描图像,由于能够清晰辨别膀胱壁层次结构,故显示出对膀胱肿瘤浸润深度进行评估的能力。本文主要就原理、研究现状及其目前应用过程中存在的问题和展望等方面对以上技术进行综述。
