Decreased diffusivity along the perivascular spaces in bipolar disorder: an MRI-based cross-sectional and Mendelian randomization study

Translational Psychiatry
The pathophysiology of bipolar disorder (BD) remains unclear. We investigated whether diffusion tensor imaging along perivascular spaces (DTI-ALPS), a putative MRI marker of glymphatic function, is altered in BD and whether this index relates to ...

Do We Really Know How to Manage Anticoagulated Patients for Periodontal Nonsurgical Therapy? An Observational Cohort Study

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objectives The aim of this work is to assess and compare the impact of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKA) during and immediately after periodontal nonsurgical therapy. Materials and Methods A prospective observational cohort study was conducted with patients who presented a history of cardiovascular disease ...

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,

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.

Macrostructural and microstructural alterations of hippocampal subregions in T2DM: NODDI provides added value to DTI and volumetric analyses

Brain Research Bulletin
Objective: We explored macrostructural and microstructural changes in the hippocampal subregions of patients with type 2 diabetes mellitus (T2DM) and compared the effectiveness of neurite orientation dispersion and density imaging (NODDI) with that of ...

DTI-based upper limit of voxel free water fraction

, 2018
BackgroundFree water (FW) in neuroimaging is non-flowing extracellular water in the cranium and brain tissue, and includes both cerebral spinal fluid (CSF) and fluid in intercellular space or edema. For a region such as a voxel (spatial unit of measurement in neuroimaging), the FW fraction is defined as the volume fraction of FW within that volume ...

Characterization of postnatal brain injury and behavioural deficits in a rat model of placental insufficiency‐induced fetal growth restriction

The Journal of Physiology, EarlyView.
Abstract figure legend Fetal growth restriction (FGR) is a common pregnancy complication associated with long‐term neurodevelopmental impairments. Using the reduced uterine perfusion pressure (RUPP) rat model of placental insufficiency‐induced FGR, this study demonstrates that FGR leads to persistent anatomical, histological and behavioural ...

Dissecting the Strain and Sex Specific Connectome Signatures of Unanesthetized C57BL/6J and DBA/2J Mice Using Magnetic Resonance Imaging

Genes, Brain and Behavior, Volume 25, Issue 4, August 2026.
C57BL/6J and DBA/2J mice were used to investigate strain and sex‐specific features of the brain connectome in awake animals using magnetic resonance imaging (MRI). By combining resting‐state and diffusion MRI, we found significant differences in the motor, sensory, limbic, and salience networks between C57BL/6J and DBA/2J mice.
