ANPEP and neoplasm: In another positron emission tomography/magnetic resonance imaging (PET/MRI) experiment by Kis et al. the APN/CD13 target selectivity of the following four different [68Ga]Ga-labelled NGR peptide compounds was compared using chemically induced syngeneic He/De and Ne/De preclinical rat tumour models: [68Ga]Ga-NOTA-c(NGR), [68Ga]Ga-NODAGA-c(NGR), [68Ga]Ga-NODAGA-c(NGR) (MG1) or [68Ga]Ga-NODAGA-c(NGR) (MG2) (as exhibited in Table 1) [38].
