High Resolution Diffusion Tensor Imaging of Brainstem Nuclei Across the Healthy Lifespan

M. Y. Soliman, Nnemdi Osadunkwu, Pablo Stack-Sánchez, Nashwan Naji et autres

Motivation: Brainstem nuclei are understudied in brain development/aging due to typically low spatial resolution of diffusion MRI. Goal(s): To investigate micro-structural changes with age/sex in red nucleus and substantia nigra across the lifespan. Approach: Diffusion tensor imaging was acquired with 1 mm³ …

Diffusion time effects over the adult lifespan indicates persistent zone‐specific microstructural alterations in the human prostate with aging

Peter Seres, Adam Kinnaird, Christopher Fung, Thorsten Feiweier et autres

PURPOSE: The purpose of this study was to investigate microstructural changes in the aging adult prostate by comparing the effects of varying diffusion times using diffusion MRI, and to provide an age-related benchmark for future prostate cancer studies. METHODS: -weighted image. Volume …

Quantitative MRI of the Prostate with Age: T1 Relaxation, T2 Relaxation, Mean Diffusivity, and Volume

Xiao Ma, Peter Seres, Adam Kinnaird, Christopher Fung et autres

Motivation: T1 relaxation, T2 relaxation, mean diffusivity (MD) and volume can offer valuable information about prostate tissue remodeling that may occur with cancer and aging. Goal(s): These age relationships are relevant for identification of cancer thresholds, but also provide insight on unique …

Age-related time-dependent diffusivity changes within healthy human prostate

Xiao Ma, Peter Seres, Adam Kinnaird, Christopher Fung et autres

Diffusion MRI is used daily in prostate cancer diagnosis. Modification of the diffusion time can probe alterations in prostate microstructure dimensions that may occur with aging or cancer. The mean diffusivity (MD) difference between ‘long’ diffusion time stimulated echo acquisition mode (STEAM) …
