Group comparison and brain chart modeling are integrated to examine these changes. Qualitative voxel-wise group comparison among different age and gender groups are analyzed.

A significantly decrease in metabolism is observed in males aged 45 to 70 compared to females. Metabolic aging trajectories and centile scores demonstrate a gradual decline across the total cortical, subcortical and most brain regions. Additionally, brain regions with maximum values (not at age 18), extreme age points, and their corresponding ages were identified. Specifically, only 12 brain regions exhibited values higher than those at age 18, and only 8 regions displayed extreme points throughout the aging process.&lt;/p&gt;&lt;h3 data-test=\"abstract-sub-heading\"&gt;Conclusion&lt;/h3&gt;&lt;p&gt;In summary, our large population study identifies a distinct pattern of brain glucose metabolism during aging that varies between men and women, with two critical age periods based on gender: 45–49, and 70–75. We establish benchmark trajectories for various brain regions, which could serve as references in future aging studies of healthy populations.
