Abstract: Utilizing novel imaging modalities for defining response and predicting long-term outcome after treatment may have a
significant impact on cancer patient management. 18F-FDG PET/CT has great potential for use in early assessment of response to
cancer therapy. However, the lack of a general consensus on a specific set of response criteria makes adoption of PET difficult for
the oncology community. The optimal time after initiating therapy for as-sessing response to treatment also has yet to be clearly
determined.  (ajnmmi1107001).
