Brain morphometrics and aging with paired 3T and 7T structural MRI: 7T reduces reqiured sample size and improves statistical significance.
Abstract
During normal aging, it has been observed that brain regional volume and thickness can be altered due to atrophy. While both 3 Tesla (3T) and 7 Tesla (7T) MRI are used to study such changes, it is unknown how individual brain morphology is characterized differently when 7T MRI allows for higher‐resolution and higher tissue contrast images. In this study, we employ a large cohort of healthy subjects that have undergone both 3T and 7T MRI scans to investigate how 7T MRI improves correlation strength between brain morphometrics and aging.

Research summary
The paper investigates the relationship between brain morphometrics and aging using advanced MRI technology, which is relevant to understanding the biological processes of aging. However, it primarily focuses on imaging techniques rather than addressing the root causes of aging or proposing interventions for lifespan extension. The findings may contribute to the field of aging research but do not represent a significant breakthrough or transformative work.
