Figure 1

In (a) the compartment models for a targeted tracer in a cancerous region and a reference region (one void of specific receptor) are presented in blue boxes in the “Tumor” and “Reference Tissue” labeled dashed black line boxes, respectively. The compartment models for an untargeted tracer in the two regions are presented in red boxes. A white light image of the experimental mouse setup is provided in (b). The skin is removed from the tumor (identified by the solid white arrow) and the surrounding potential reference tissues (the dashed white arrow is pointing to muscle adjacent to the tumor, presumably void of epidermal growth factor receptor).
