| 1 | 4 | 8 | 24 | |
| Scintigraphic images | 2.4 ± 0.2 | 2.8 ± 0.3 | 3.3 ± 0.4a | 2.8 ± 0.3 |
| Biodistribution | 1.9 ± 0.2b | 2.7 ± 0.4b | 2.5 ± 0.8b | 5.0 ± 1.3 |
Data are expressed as the mean ± the standard deviation of the mean (n = 6).
a
Represents significant difference when compared with tumor-to-muscle ratio at 1 h post-injection.
b
Represents significant difference when compared with tumor-to-muscle ratio at 24 h post-injection.
