Abstract
Methods for reliable identification of low-contrast lesions within a tissue of a subject comprise delivering an excitation signal to the tissue, wherein the excitation signal is selected to stimulate tissue to produce autofluorescence and/or reflectance. The autofluorescence and/or reflectance is detected, and ratiometric images are produced based on the autofluorescence and/or reflectance images. An imaging system is provided which is configured to carry out such methods, irradiating tissue at a various possible excitation wavelengths, such as UV excitation wavelengths below 300 nm, to elicit fluorescence from specific native fluorophores.
