Table 2 Number of decays expected in standard scan conditions and time used to acquire an equal amount of positron decays for each radionuclide.

From: Comparison of scandium-44 g with other PET radionuclides in pre-clinical PET phantom imaging

Nuclide Positron annihilations in 1200 s for 3.7 MBq Time to acquire the same number of positron annihilations as 18F (s)
18F 4.03 × 109 1200
68Ga 3.57 × 109 1376
64Cu 0.774 × 109 6506
