This paper characterizes orientation-dependent anisotropic R2 profiles in callosal segments using DTI data, showing increases in R2 with b-value and fiber tract position.

This paper compares orientation-dependent transverse relaxation at 3T and 7T in human brain white matter, finding that the magic angle effect, not susceptibility, is the primary mechanism.

This paper introduces a decentralized linear mixed-effects model for neuroimaging analysis, enabling large-scale collaboration without data pooling, and shows it achieves similar performance to centralized models.

This work proposes a decentralized method for brain age estimation using MRI data and shows it achieves similar performance to centralized models.
