High‐Resolution IVIM MRI Characterizes Diffusion–Perfusion Properties of the Parasagittal Dura

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Parasagittal dura demonstrates intermediate diffusion and elevated perfusion‐related IVIM metrics compared with brain parenchyma, reflecting its unique microfluidic environment at the CSF–dura interface. IVIM imaging of the parasagittal dura provides a rapid, noncontrast MRI approach to assess dural fluid transport and may offer a potential imaging ...

Image_4_Fixel-Based Analysis and Free Water Corrected DTI Evaluation of HIV-Associated Neurocognitive Disorders.tiff

, 2021
Background: White matter (WM) damage is a consistent finding in HIV-infected (HIV+) individuals. Previous studies have evaluated WM fiber tract-specific brain regions in HIV-associated neurocognitive disorders (HAND) using diffusion tensor imaging (DTI).

A Novel MR Elastography Device for Preclinical Applications From Spheroids to Rodents: Design, Validation, and Performance Evaluation

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
MR elastography (MRE) noninvasively assesses tissue biomechanics, but preclinical research suffers from diverse hardware solutions, hindering reproducibility and comparability. This study introduces a versatile preclinical MRE device for imaging rodents, ex vivo samples, and spheroids/organoids.

Predicting glioblastoma recurrence from preoperative MR scans using fractional-anisotropy maps with free-water suppression.

, 2020
Diffusion tensor imaging (DTI), and fractional-anisotropy (FA) maps in particular, have shown promise in predicting areas of tumor recurrence in glioblastoma.

Multidimensional MRI Reveals Cellular‐Scale Microstructural Phenotypes in Human Brain Aging

Aging Cell, Volume 25, Issue 11, November 2026.
Multidimensional diffusion–relaxation MRI reveals that normative brain aging involves progressive reorganization of cellular‐scale microstructure—marked by expanding length‐scales, increasing heterogeneity, and breakdown of microscopic restriction—across cortical and subcortical gray matter and white matter throughout the adult lifespan.

Sensitivity of restriction spectrum imaging to memory and neuropathology in Alzheimer’s disease

Alzheimer’s Research & Therapy, 2017
Background Diffusion imaging has demonstrated sensitivity to structural brain changes in Alzheimer’s disease (AD). However, there remains a need for a more complete characterization of microstructural alterations occurring at the earliest disease stages,

Distinguishing Early from Late Mild Cognitive Impairment Using Magnetic Resonance Free-Water Diffusion Tensor Imaging

NeuroSci
Mild Cognitive Impairment (MCI) is a transitional stage between normal aging and Alzheimer’s disease. Differentiating early MCI (EMCI) from late MCI (LMCI) is crucial for early diagnosis and intervention.
