Metabolite T1 and T2 Relaxation Times in Healthy Aging

Key Points

T1 and T2 relaxation times of metabolites correlate with age in a large cohort, showing significant findings for tNAA2.0 and tCr3.0.
The analysis identified a correlation between T1 and T2 of metabolites in both the corpus callosum and posterior cingulate cortex.
Statistical evaluations were utilized to explore relationships between T1, T2, and tissue water across different metabolites.
Findings emphasize the importance of understanding metabolite relaxation over the lifespan to inform future studies on metabolite concentrations.

Abstract

Motivation: Metabolite relaxation measurements vary with age, in patterns that are distinct from changes in water relaxation, presumably reporting on specific cellular microenvironments. Goal(s): To investigate metabolite T1 and T2 relaxation times at 3 T across the lifespan. Approach: T1 and T2 relaxation times of metabolites were measured from an aging cohort consisting of 101 participants. Statistical analyses were conducted to identify correlations between T1/T2 and age, and between T1 and T2 for each metabolite of interest and tissue water. Results: T1 and T2 were correlated in the aging cohort for tNAA2.0, tCr3.0 and Glx in both CSO and PCC. Impact: Understanding the life-course of metabolite relaxation times is a critical pre-requisite to studies of metabolite concentration across the lifespan. We report correlations of T1 and T2 of metabolites with age, and between T1 and T2 in a large aging cohort.
