Paper Abstract

Fluorescence-labeled molecular probes can be used during endoscopy for early cancer detection. As many tumors express multiple cell surface markers and these molecular signatures are heterogeneous across patients, simultaneous imaging of numerous different molecular targets is important for increasing the sensitivity of early cancer diagnosis and personalized treatment. For this purpose, a wide-field, multi-spectral fluorescence-reflectance scanning fiber endoscope (SFE) has been developed. Using a set of calibrated fluorescent test targets at in vivo dye concentration, algorithms and methodologies were developed and demonstrated. Preliminary results showed the promise of fluorescence molecular imaging in clinical applications using the multi-spectral SFE.
