In addition, preclinical or clinical findings indicate that differences in the uptake of other established tracers, such as (2-[18F]fluoroethyl)choline, 6-[18F]fluoro-3,4-dihydroxyphenylalanine ([18F]FDOPA) or [18F]DPA-714, could be used to infer the IDH mutation status in gliomas [36,37]. Here, IDH2 is linked to glioma.
