Baseline (day 1) and follow-up (day 57) FDG TOF PET scan of the patient liver compared to the ⁹⁰Y TOF PET raw activity distribution measured after ⁹⁰Y-labeled SIR-Spheres therapy (day 15). A nice tumor response was noted in the region of high absorbed dose (104 Gy), while a tumor progression occurred in the region not targeted by the ⁹⁰Y-labeled SIR-Spheres. Absorbed doses (AD) were computed using the ⁹⁰Y 4-mm voxel S values with (spatial resolution deconvolution) SRD and in parentheses without SRD.
