Research Abstract |
This study evaluated the potential usefulness of[^<18> F] Choline as a new cancer tracer for PET. The uptake of[^<18> F] Choline and[^<18> F] FDG are cell cycle dependent, are associated with the proliferative activity of the tumor seen during PET imaging. The average SUVs of[^<18> F] FDG for the gingival cancer infiltrated jawbone was markedly higher than that for the tongue. The average SUVs of[^<11> C] or[^<18> F] Choline were showing no significant difference between the tongue and gingival cancer, and the same level as[^<18> F] FDG uptake for the tongue cancer. It seems that[^<18> F] Choline is not well incorporated to the osteogenetic cell and the osteoclast related to bone metabolism but accumulation for the cancer cells.
