Retention time of the 18F-NOTA-CREKA (a), 18F-NOTA-LP (b), and 18F-NOTA-iCREKA (c) and their in vitro stability in PBS and serum. (d) 18F-NOTA-CREKA, (e) 18F-NOTA-LP, and (f) 18F-NOTA-iCREKA were the in vivo stability tests in the blood and tumor at 30 min after vein injection of fluorine-18 labeled peptides.
