荧光寿命成像(FLIm)是一种能够在临床环境中实时评估组织特性的光学光谱成像技术。无标记FLIm对病理条件引起的组织结构和生物化学变化敏感,从而提供光学对比以识别和监测疾病进展。在过去的二十年中,技术和方法的进步使得FLIm仪器的开发能够与标准临床工作流程兼容,用于实时、原位、介观成像。在此,我们回顾了介观FLIm的基本工作原理,讨论了当前临床FLIm仪器的技术特点,强调了最常用的分析方法来解释荧光寿命数据,并讨论了FLIm在外科肿瘤学和心血管诊断学中的最新应用。最后,我们总结了临床FLIm的未来发展方向的展望。
Fluorescence lifetime imaging (FLIm) is an optical spectroscopic imaging technique capable of real-time assessments of tissue properties in clinical settings. Label-free FLIm is sensitive to changes in tissue structure and biochemistry resulting from pathological conditions, thus providing optical contrast to identify and monitor the progression of disease. Technical and methodological advances over the last two decades have enabled the development of FLIm instrumentation for real-time, in situ, mesoscopic imaging compatible with standard clinical workflows. Herein, we review the fundamental working principles of mesoscopic FLIm, discuss the technical characteristics of current clinical FLIm instrumentation, highlight the most commonly used analytical methods to interpret fluorescence lifetime data and discuss the recent applications of FLIm in surgical oncology and cardiovascular diagnostics. Finally, we conclude with an outlook on the future directions of clinical FLIm.
