Representative PET/CT images and quantitative analyses of patients from Group 3. The patient was scanned before and after treatment. Pre-treatment scan data were reconstructed using the clinical reconstruction algorithm (upper panel). Post-treatment scan data were reconstructed using the clinical (middle panel) and OSEM (lower panel) algorithms. Without EQ.PET, the ΔSUVmax and ΔSUVmax% of the two different reconstruction algorithms showed different therapy response results. With EQ.PET, the ΔSUVmax and ΔSUVmax% of the two different reconstruction algorithms showed consistent results
