Table 3 Number of discordances between the OSEM1/OSEM2 scenario and other scenarios involving reconstruction inconsistency for EORTC and PERCIST therapeutic evaluations

From: EORTC PET response criteria are more influenced by reconstruction inconsistencies than PERCIST but both benefit from the EARL harmonization program
