Negative correlation between plasma glucose levels and ¹⁸F-FDG uptake in whole-brain voxelwise analysis with age and gender adjustment.

<p>Significant clusters at a threshold of cluster-corrected <i>p</i> < 0.05 showing negative correlation of plasma glucose levels with FU values are displayed on the SPM glass brain (left side) and on the standard brain (right side) in the MNI space. They extended to the precuneus and lateral parietotemporal regions. The yellow–red scale represents the magnitude of <i>p</i> values. FU: normalized values of ¹⁸F-FDG uptake using the whole cerebral cortex as a reference region, R: right, L: left, SPM: Statistical Parametric Mapping, MNI: Montreal Neurological Institute.
