Diffusion tensor imaging study of brain precentral gyrus and postcentral gyrus during normal brain aging process
Abstract Objective To study the changes of white matter tracts in precentral gyrus and postcentral gyrus during normal brain aging process by analyzing fractional anisotropy (FA) values obtained from diffusion tensor imaging (DTI) technology. Methods Magnetic resonance imaging (MRI) and diffusion te...

Methods Magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) were conducted on 120 healthy right‐handed subjects.

Results For each age group, the FA values of white matter in precentral gyrus and postcentral gyrus are statistically different (p < .05) in both left and right sides of the brain across different age groups and genders. Additionally, the FA values are statistically different (p < .05) between two young and senior age groups across different genders, brain regions, and hemispheres. Conclusion The FA values of precentral gyrus and postcentral gyrus are statistically different across genders, age groups, and hemispheres. Additionally, the FA values of both precentral gyrus and postcentral gyrus decrease over time, which is a strong indication of aging.https://doi.org/10.1002/brb3.1758age‐related analysisbrain imagingdiffusion tensor imagingfractional anisotropy valuemagnetic resonance imagingpostcentral gyrus |
