High-fidelity diffusion tensor imaging of the cervical spinal cord using point-spread-function encoded EPI

NeuroImage, 2021
Diffusion tensor imaging (DTI) of the spinal cord is technically challenging due to the size of its structure and susceptibility-induced field inhomogeneity, which impedes clinical applications.

Free water: A marker of age-related modifications of the cingulum white matter and its association with cognitive decline.

PLoS ONE, 2020
Diffusion MRI is extensively used to investigate changes in white matter microstructure. However, diffusion measures within white matter tissue can be affected by partial volume effects due to cerebrospinal fluid and white matter hyperintensities ...

Free water corrected diffusion tensor imaging discriminates between good and poor outcomes of comatose patients after cardiac arrest [PDF]

, 2023
Objectives: Approximately 50% of comatose patients after cardiac arrest never regain consciousness. Cerebral ischaemia may lead to cytotoxic and/or vasogenic oedema, which can be detected by diffusion tensor imaging (DTI). Here, we evaluate the potential

Diffusion tensor free water MRI predicts progression of FLAIR white matter hyperintensities after ischemic stroke

Frontiers in Neurology, 2023
BackgroundThe progression of FLAIR white matter hyperintensities (WMHs) on MRI heralds vascular-mediated cognitive decline. Even before FLAIR WMH progression, adjacent normal appearing white matter (NAWM) already demonstrates microstructural ...

Image_2_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).
