This paper introduces RISH-GLM, a method to harmonize diffusion MRI data across sites without requiring matched training subjects, showing effectiveness with unmatched groups and multiple sites.

This study examines how spaceflight duration and prior experience affect brain structure in astronauts, finding greater ventricular expansion and white matter decline with longer missions and more prior flights.

This study examines the relationship between amyloid-PET signals in white matter and microstructural changes like free water and fiber integrity, finding that free water and WMH volume are more closely linked to Aβ-PET in WMH regions.

This study uses diffusion MRI to detect neuroinflammation in vivo in rats after a lipopolysaccharide challenge, showing diffusivity changes correlate with microglial morphology.

This study examines how brain structure relates to balance in young and older adults under different sensory conditions, finding associations between cortical thickness, gyrification, and white matter microstructure with balance performance.

This study investigates the role of superficial white matter microstructure in processing speed in cerebral small vessel disease, finding that free-water measures in SWM strongly correlate with cognitive decline.

This study examines how brain structure relates to dual task walking in young and older adults, finding age-specific associations between brain atrophy and gait performance during cognitive tasks.

This paper develops a deep learning method to segment brain tissue from diffusion MRI without anatomical registration, achieving high accuracy on both HCP and clinical data.

The paper maps individual deviations from normative brain structure in schizophrenia patients and finds high heterogeneity, with most patients showing infra-normal deviations in at least one region.

This study uses free-water imaging to find microstructural white matter differences in chronic schizophrenia patients compared to controls, with associations to subcortical structures and clinical symptoms.

This study shows that limbic white matter microstructure and hippocampal subfield volumes together predict verbal learning rates in older adults, with an interaction effect observed.

This study uses diffusion MRI tractography to map individual variations of the human corticospinal tract and hand-related motor fibers, creating a database of their volume, length, and biophysical parameters.
