Metabolism

Fluorodopa F 18 is decarboxylated by aromatic amino acid decarboxylase (AADC) in the striatum to fluorodopamine F 18. Fluorodopamine F 18 is then further metabolized by monoamine oxidase (MAO) to yield [18F] 6-fluoro-3,4-dihydroxyphenylacetic acid, then subsequently by COMT to yield [18F]6-fluorohomovanillic acid.1
