Table 3. Overview of relative differences in % between the differently reconstructed PETs and regions.
Note the differences of SUV-underestimation in the posterior lung parts while the overestimations in the anterior regions do not change significantly. P-Values describe the significance of differences between the particular lung regions in the different PET images. The SUVs of PETCTAC_MRLUNG_NOBONE and PETMRAC images did not differ significantly in any region.
