Abstract
Fluorescence imaging can result in poor tumor contrast due to non-specific probe accumulation of receptor targeted probes. Here we show using preclinical and clinical studies that fluorescence lifetime (FLT) imaging can significantly improve the sensitivity and specificity for tumor detection using epidermal growth factor receptor (EGFR) targeted near infrared probes. We also show that FLTs in tissue are highly correlated with receptor expression levels, thereby enabling quantification of receptor quantification in vivo. Ongoing efforts in our group towards the translation of FLT imaging for intraoperative image guidance during head and neck surgeries will also be discussed.
