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 |
44gSc | 4.07 × 109 | 1190 |
