Background/aim: Angiogenesis imaging has been a valuable complement to metabolic imaging with 2-deoxy-2-[F]fluoroglucose (FDG). In our longitudinal study, we investigated the tumour heterogeneity and the relationship between FDG and [Ga]Ga-NODAGA-c(RGDfK) (RGD) accumulation in breast cancer xenografts.
Materials And Methods: Two groups of cell lines, a fast-growing (4T1) and a slow-growing cell line (MDA-MB-HER2+), were inoculated into SCID mice.
