Figure 12: (A,B): A 52-year-old man with metastatic CRC imaged with FDG PET / CT before and after targeted therapy. Fusion PET / CT study (A) prior to targeted therapy shows an FDG-avid metastatic retroprostatic nodule (arrow). There is significant reduction in the metabolism and size of the recurrent nodule (arrow) on the post-therapy follow-up PET / CT image (B), suggesting therapeutic response
