Noninvasive Imaging of Fluorescent Reporters in Small Rodent Models Using Fluorescence Molecular Tomography

: The capacity to combine noninvasive whole animal imaging of genetic reporters and exogenously added probes in a single animal makes fluorescence imaging a powerful tool for investigating molecular events in live animals in preclinical research. However, the adsorption and diffraction properties of light passing through tissues mean that the choice of reporters, models, and imaging systems needs to be carefully considered. Here, we describe approaches to design and run experiments incorporating noninvasive whole animal fluorescence imaging into small animal imaging studies.
