Abstract: Introduction: An efficient fully automated method for the radiosynthesis of enantiomerically pure O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET) using the GE TracerLab FXFN synthesis module via the O-(2-tosyloxyethyl)-N-trityl-L-tyrosine tert-butylester precursor has been developed. Methods: The radiolabelling of [18F]FET involved a classical [18F]fluoride nucleophilic substitution performed in acetonitrile using potassium carbonate and Kryptofix 222, followed by acid hydrolysis using 2N hydrochloric acid. Results: [18F]FET was produced in 35±5% (n=22) yield non-decay-corrected (55±5% decay-corrected) and with radiochemical and enantiomeric purity of >99% with a specific activity of >90 GBq/μmol after 63 min of radiosynthesis including HPLC purification and formulation. Conclusion: The automated radiosynthesis provides high and reproducible yields suitable for routine clinical use. © 2011 Elsevier Inc.
