Spatial Image Gradient Estimation From the Diffusion MRI Profile

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2980-2991, May 2026.
ABSTRACT Purpose In the course of diffusion, water molecules encounter varying values for the relaxation‐time properties of the underlying tissue. This factor, which has rarely been accounted for in diffusion MRI (dMRI), is modeled in this work, allowing for the estimation of the gradient of relaxation‐time properties from the dMRI signal.

Main Paths of Brain Fibers in Diffusion Images Mixed with a Noise to Improve Performance of Tractography Algorithm-Evaluation in Phantom [PDF]

open access: yesJournal of Biomedical Physics and Engineering
Background: Some voxels may alter the tractography results due to unintentional alteration of noises and other unwanted factors.Objective: This study aimed to investigate the effect of local phase features on tractography results providing data are mixed

Psychostimulant treatment uniquely reduces left uncinate fasciculus microstructural integrity in ADHD youth with a familial risk for bipolar I disorder: a 12‐week DTI study

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 5, Page 696-706, May 2026.
Background Bipolar I disorder (BD) is associated with reduced white matter microstructural integrity in the uncinate fasciculus (UF), a primary fiber tract connecting frontolimbic systems. Although familial history for BD, attention‐deficit/hyperactivity disorder (ADHD), and psychostimulants are important risk factors implicated in BD pathoetiology ...

Structuro‐Functional Differentiation and Coupling of Gyri and Sulci in the Neonatal Cortex

open access: yesHuman Brain Mapping, Volume 47, Issue 6, April 15, 2026.
The cortical gyro/sulcal regions are defined in each neonatal brain based on multi‐modal MRI images, and both structural and functional connectivity matrices among gyro‐sulcal regions are constructed and adopted to unveil the connectivity strength differences and coupling characteristics between gyri and sulci in neonatal brains.
