Table 2.

ROI quantification (mean ± SD of the uptake value (kBq/ml) in different ROIs) for the original whole body PET image and the corrected one using the GTM, the 2D global and the 3D local MMA approach. Note that there is no SD in the case of the GTM approach since it is a ROI based PVE correction approach.

Activity (kBq/ml)	ROI lung	ROI lesion	ROI bone
ORIGINAL PET	1.5 ± 0.1	8.9 ± 1.4	5.2 ± 0.5
GTM	1.2	10.9	5.5
2D GLOBAL	1.3 ± 0.3	10.3 ± 1.6	6.7 ± 1.7
3D LOCAL	1.4 ± 0.1	12.8 ± 1.9	5.3 ± 0.6
