This is evident by the observations that with no additional linker between the triazole ring and the FAP-targeting pharmacophore, [68Ga]Ga-AV01030 showed relatively higher tumor uptake and tumor-to-background (bone, muscle and blood) contrast ratios in both tested tumor models than those of [68Ga]Ga-AV01017 and [68Ga]Ga-AV01038. This evidence concerns the gene FAP and neoplasm.
