Abstract

O-(2-[18F]Fluoroethyl)-l-tyrosine ([18F]FET) has become one of the most successful amino acid tracers for human brain tumor imaging with positron emission tomography (PET). Facile fully automated radiosynthesis and quality control (QC) of [18F]FET using our home-built automated multi-purpose 18F-radiosynthesis module are described. [18F]FET was produced in 75–80 min overall synthesis time with 20–25% radiochemical yield decay corrected to end of bombardment (EOB), based on H[18F]F. The radiochemical and enantiomeric purities were >99%, and the molar activity (Am) was 189–411 GBq/μmol at EOB. The [18F]FET dose meets all QC criteria for clinical use, and is suitable for clinical PET study of brain tumor.
