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.

The paper develops a high-dimensional mediation analysis method for brain connectivity networks and applies it to pediatric ALL data, finding significant mediation effects of brain connectivity on visual processing speed.

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.

The paper evaluates tractography methods by analyzing a simulated dataset, finding that most algorithms generate many false-positive connections.
