Table 2. Regional K*FDG, K1/k2, k3 and k4 estimates of [18F]FDG obtained from the mice scanned over 90 min using a 3-compartment model and liver input function.
Region | K*FDG | K1/k2 | k3 | k4 |
Cortex | 0.057 [0.049–0.070] | 0.326 [0.273–0.371] | 0.183 [0.149–0.252] | 0.044 [0.034–0.053] |
Caudate-putamen | 0.067 [0.055–0.087] | 0.366 [0.288–0.421] | 0.194 [0.147–0.308] | 0.039 [0.032–0.047] |
Cerebellum | 0.072 [0.058–0.095] | 0.341 [0.261–0.425] | 0.224 [0.150–0.321] | 0.052 [0.038–0.063] |
Data are expressed as mean [min-max]; n = 10 K*FDG, uptake constant (ml/min/g); K1, uptake rate constant (ml cm−3 min−1); k2, clearance rate constant (min−1); k3, phosphorylation rate constant (min−1); k4, dephosphorylation rate constant (min−1); min, minimum; max, maximum.
