Visualizations of the molar percentage excess (MPE) for 13C6-Phe and 13C6-Tyr and the ratio of MPE (Tyr) to MPE (Phe) in representative tumor tissues at 10, 30, and 60 min after tracer injection and at 10 min of sham group. Their co-registered, hematoxylin and eosin stained (H&E) images are shown on the top. A magnification of the ratio of MPE (Tyr) to MPE (Phe) in one representative tissue section at 60 min and its co-registered H&E image is shown on the right
