Adjusted linear regression analysis of SUVbw against BGL and serum ketones performed on a voxel-by-voxel basis and projected onto a cortical surface map to aid localisation using CapAIBL. a t-score map for significance of change in SUVbw related to BGL. The strongly negative t-scores (deep blue) across the entire cortex indicate increasing BGL suppresses FDG uptake across the entire cortex; b t-scores for serum ketones are also significant across the entire cortex, confirming that higher serum ketones suppress SUVbw in addition to the suppressive effect of increasing BGL; c plot of the value of the coefficient for BGL in the multiple linear regression equation for each voxel, showing that this coefficient has greater magnitude (red) in the region of the precuneus; d plot of the value of the coefficient for serum ketones, showing that this also has greatest magnitude in the precuneus
