Fig. 3From: Advances of radiolabeled GRPR ligands for PET/CT imaging of cancersCoronal MIP preclinical PET/CT images showing tracer distribution in PC-3 xenografted NOD-SCID mice. The animals were injected with 0.18Â nmol of 55Co-NOTA-PEG2-RM26 (approx. 3Â MBq) and scanned at (a) 3Â h and (b) 24Â h pi. The tumor is shown by the arrow. With permission, from Ref.
