Synthetic MR is an emerging technique capable of providing quantitative relaxation maps and conventional contrast weighted images simultaneously. This study aims to study the relaxation and volumetric characteristics in the ageing process with synthetic MRI. We found volume is a primary metrics for assessing brain ageing and relaxometry may provide additional quantitative biomarkers and possible implications for studying brain ageing.
