Data for the paper : Age-Trajectories of Higher-Order Diffusion Properties of Major Brain Metabolites in Cerebral and Cerebellar Gray Matter Using In Vivo Diffusion-Weighted MR Spectroscopy at 3T

Quantified metabolite (total N-acetyl-aspartate, total Choline and total Creatine) signals for different participant diffusion-weightings are stored in the dMRS_aging_fitResults file. Data is stored in 'xlsx' format including the participants' demographic information (age and sex).The b-values for all directions, obtained from the gradient chronograms, are stored in the b_values_from_chrono file.The JSON file contains the diffusion model fitting results using the nonlinear least squares method.
