Metabolic response assessment with 18 F-FDG PET/CT: inter-method comparison and prognostic significance for patients with non-small cell lung cancer

Conclusions There was a modest discrepancy in metabolic response rates between PM and UM criteria, though both could offer predictive classification for survival. The percentage decrease provides an ordinal value that correlates with prolonged survival, recommending 75 % as the optimal threshold at identifying better responders.
