Table 1. Characteristics of ¹⁸F-RGD-K5 and ⁶⁸Ga-RGD.

Radio-tracers	Radionuclide	Molecule
¹⁸F-RGD-K5	Fluorine-18 ½ half-life = 109.8 min Positron yield = 96.86% Mean energy E_β = 0.250 MeV Maximum energy E_βmax = 0.634 MeV
⁶⁸Ga-RGD	Gallium-68 ½ half-life = 68 min Positron yield = 89.14% Mean energy E_β = 0.829 MeV Maximum energy E_βmax = 1.899 MeV

The chemical structure in green corresponds to the cyclic tripeptide RGD Arginin-Glycin-Aspartic acid (c(RGDfK), the orange structure corresponds to a sugar, the purple structure to the triazole, the blue structure to the NODAGA chelate and in red the radionuclide.
