Cerebral metabolism of 6-[18F]fluoro-L-3,4-dihydroxyphenylalanine in the primate.

Abstract

The tracers 6-[18F]fluoro-L-3,4-dihydroxyphenylalanine (6-[18F]fluoro-L-DOPA) and L-[14C]DOPA were injected simultaneously into rhesus monkeys, and the time course of their metabolites was measured in the striatum and in the occipital and frontal cortices. In the striatum, 6-[18F]fluoro-L-DOPA was metabolized to 6-[18F]fluorodopamine, 3,4-dihydroxy-6-[18F… (More)
