A primary lung tumor in a dog treated with intensity‐modulated radiation therapy was imaged approximately 6 weeks and 1‐year posttreatment with combined positron emission tomography (PET) and computed tomography, utilizing the radiotracers 18 F‐fluorodeoxyglucose and 18 F‐fluorothymidine. These two tracers allowed discrimination of tumor from inflammation, and demonstrated spread of tumor along airways over time after treatment. Fusion of functional imaging with anatomic imaging is a useful tool, particularly in the field of oncology, with the potential for PET markers that delineate tumor from normal or reactive tissue, and potential or actual response to therapy.
