Comparisons in tumor uptake (A), urine excretion (B) and intestine accumulation (C) at 4 h post-injection among 99mTc(EDDA)-HYNIC-GGNle-CycMSHhex (blue), 99mTc-(Arg11)CCMSH (pink), 99mTc(CO)3-Pz-βAla-Nle-cyclo[Asp-His-DPhe-Arg-Trp-Lys]NH2 (green) and 99mTc-CGCG-NDPMSH (red). Data of 99mTc-(Arg11)CCMSH, 99mTc(CO)3-Pz-βAla-Nle-cyclo[Asp-His-DPhe-Arg-Trp-Lys]NH2 and 99mTc-CGCG-NDPMSH were cited from references 18, 26 and 32 for comparison.
