Two normal mice were injected with 8.9 MBq 18FDG and 9.4 MBq 18F, respectively. One and a half hours later the mice were centered inside the gantry and imaged for 1 hour. CT transmission scans of the mice were performed on a MicroCAT™ II tomograph with the same protocol as the CT scan for the image quality phantom. The PET data were reconstructed with FORE+2DFBP (with a ramp filter cutoff at the Nyquist frequency) and MAP reconstructions (β = 0.01) with all available corrections applied, including attenuation and scatter.
