ALB and neoplasm: In the biodistribution study, [111In]In-DOTAGA-ALB-IS showed a higher tumor accumulation and lower renal uptake than IS-[111In]In-DOTADG-ALB, suggesting different pharmacokinetics of the radioligands based on their albumin-binding affinities modified by the arrangement of the IS ligand, DOTA, and Lys-IPBA.
