Felipe Godinez wins the Valentin T. Jordanov Radiation Instrumentation Award for building the first dedicated PET scanner for mouse paws (pawPET)

Brief description

Our group is validating imaging modalities such as small-animal PET/CTand MRI for the quantification of inflammatory arthritic activity during disease progression in a  murine model. The goal of this work is to validate imaging biomarkers that may be used in pre-clinical studies of the inflammatory arthritic disease process and for monitoring of response to treatment in a non-invasive, in vivo manner. Our research group has also built the world’s first dedicated PET scanner (called ‘pawPET’) that allows for better quantification of disease activities in the joints of the mouse paw. We are also developing image processing methods that allow for the improved derivation of imaging biomarkers of inflammatory arthritis.
