Table 3 Relative difference (100% × (SUVmean_true − SUVmean_5mm)/SUVmean_true) in SUVmean values for the 4 different reconstruction algorithms generated by 5 mm mismatch between SPECT and CT. AMAP-S and AMAP-R refer to reconstructions where lesion is absent in the CT and AMAP-S CT and AMAP-R CT to lesion-present cases
