Aim: Tumor and chemo/radiotherapy-damaged brain tissues are hardly distinguishable by conventional morphological imaging. 18F-FCH was compared against 18F-FDG in the T98G glioblastoma cell line with regard to their radiopharmaceutical uptake, in order to test its diagnostic power on brain tumor lesions. Materials and Methods: Equimolar amounts of 18F-FCH and 18F-FDG were added to human glioblastoma T98G cells and human dermal fibroblasts for 20, 40, 60, 90 and 120 min of incubation. Radiopharmaceutical uptake was expressed as a percentage of the administered dose. Cold choline was used for binding competition experiments. Results: In T98G cells 18F-FCH was taken-up in higher amounts than 18F-FDG after 60 min. In fibroblasts, uptake was lower than 1% for both radiopharmaceuticals. Cold choline reduced the uptake of FCH to 1% similarly to fibroblasts. Conclusion: Our results prove the efficacy of 18F-FCH as a promising tracer, better than 18F-FDG in establishing the tumor-tobackground ratio in brain tumors.
