White Matter Tract Alterations in Bipolar Disorder: A Systematic Review and Meta‐Analysis of Diffusion Tensor Imaging Studies

Brain and Behavior, Volume 16, Issue 5, May 2026.
This systematic review and meta‐analysis synthesizes diffusion tensor imaging evidence of white matter microstructural abnormalities in bipolar disorder. Across published studies, patients with bipolar disorder showed reduced fractional anisotropy in several major white matter tracts, including the corpus callosum, cingulum bundle, corona radiata ...

Joint diffusional kurtosis magnetic resonance imaging analysis of white matter and the thalamus to identify subcortical ischemic vascular disease

Scientific Reports
Identifying subcortical ischemic vascular disease (SIVD) in older adults is important but challenging. Growing evidence suggests that diffusional kurtosis imaging (DKI) can detect SIVD-relevant microstructural pathology, and a systematic assessment of ...

Deep Learning Empowered Microstructure Codebook: New Paradigm for Multi‐Parameter Tissue Characterization Estimation

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
We propose DEMIC, a deep‐learning microstructure codebook framework for dMRI microstructure imaging: (1) accurate multi‐parameter estimation from undersampled data; (2) robust cross‐protocol and cross‐model generalization; and (3) flexible transfer to new microstructural indices via fine‐tuning.

White matter changes in recovered COVID-19 patients: insights from DTI, DKI, and NODDI metrics

Frontiers in Neurology
BackgroundCOVID-19 affects not only the respiratory system but also the central nervous system, resulting in symptoms such as anosmia and confusion. Understanding the long-term neurological effects of COVID-19 is critical for comprehensive patient care ...

High-resolution diffusion kurtosis imaging at 3T enabled by advanced post-processing

Frontiers in Neuroscience, 2015
Diffusion Kurtosis Imaging (DKI) is more sensitive to microstructural differences and can be related to more specific micro-scale metrics (e.g. intra-axonal volume fraction) than diffusion tensor imaging (DTI), offering exceptional potential for clinical
