Fig. 1From: The pons as reference region for intensity normalization in semi-quantitative analysis of brain 18FDG PET: application to metabolic changes related to ageing in conventional and digital control databasesMetabolic changes related to ageing with SPM linear regression analyses among the intensity normalization methods based on the whole grey-matter, the cerebellum and the pons for the conventional camera (FWE, p < 0.05, upper panel) and the digital camera (equivalent T-voxel level of the previous conventional analysis, lower panel). The results are represented with 3D-rendered volumesBack to article page
