Uptake of 11C-MCYS, 18F-FDG, and 11C-MET in Tumor, Inflammatory Lesion, and Muscle at 60 Minutes After Injection in Tumor-Model Mice and Inflammation-Model Mice
| Tissue | 11C-MCYS | 18F-FDG | 11C-MET |
| Tumor | 4.58 ± 0.65 | 4.32 ± 0.47 | 3.03 ± 0.79 |
| Inflammation | 1.02 ± 0.18 | 3.30 ± 0.23 | 1.62 ± 0.68 |
| Muscle | 0.63 ± 0.05 | 0.85 ± 0.13 | 0.71 ± 0.09 |
| Tumor-to-muscle ratio | 7.27 | 5.08 | 4.26 |
| Inflammation-to-muscle ratio | 1.62 | 3.88 | 2.28 |
Mice (n = 5) were killed at 60 min after injection; tissue samples were rapidly removed, and weight and radioactivity were measured. Data are average %ID/g ± SD (n = 5), or ratio.
