GRPR and neoplasm: A biodistribution comparison between [64Cu]Cu-DOTA- and [64Cu]Cu-NOTA-conjugated to an 8-Aoc-BBN(7-14)NH2 GRPR targeting moiety, as previously discussed, has demonstrated NOTA to be a more suitable complex as compared to DOTA in terms of minimizing the demetallation of [64Cu]Cu in vivo in a PC-3 tumor-bearing mouse model [17].
