This presentation overviews fluorescence lifetime spectroscopy and imaging techniques for label-free in vivo characterization of biological tissues. Emphasis is placed on recently developed devices and methods enabling real-time characterization and diagnosis of diseased tissues during clinical interventions. I will present studies conducted in animal models and human patients demonstrating the ability of these techniques to provide rapid in-situ evaluation of tissue biochemistry and their potential to guide surgical and intravascular procedures. Current results demonstrate that intrinsic fluorescence can provide useful contrast for the diagnosis of vulnerable atherosclerotic plaques, intraoperative delineation of brain tumors and head and neck tumors. Finally, I will present results from the first-in-human study that shows the potential of a multispectral fluorescence lifetime method for image-guided augmented reality in trans-oral robotic surgery (TORS).
