A simple, rapid and fully automated preparation of sodium [(18)F]fluoroacetate has been developed by taking advantage of the similarities between the reaction pathways of [(18)F]fluoroacetate and [(18)F]-2-fluoro-deoxyglucose (FDG). The automated synthesis of sodium [(18)F]fluoroacetate was achieved with a commercial [(18)F]FDG synthesizer, the TRACERlab MX(FDG). The method produced the desired compound in a short synthesis time (32 min) and with a high and reproducible radiochemical yield (50.2 +/- 4.8%, decay corrected). The radiochemical purity of sodium [(18)F]fluoroacetate was greater than 99%.
