Advanced diffusion MRI tract signatures in Alzheimer’s disease, dementia with Lewy bodies, and the FTD/PPA spectrum

NeuroImage
Alzheimer’s disease (AD), Dementia with Lewy bodies (DLB), frontotemporal dementia (FTD), and primary progressive aphasia (PPA) are heterogeneous neurodegenerative syndromes with overlapping clinical features and substantial societal burden.

Microstructure, length, and connection of limbic tracts in normal human brain development

Frontiers in Aging Neuroscience, 2014
The cingulum and fornix play an important role in memory, attention, spatial orientation and feeling functions. Both microstructure and length of these limbic tracts can be affected by mental disorders such as Alzheimer’s disease, depression, autism ...

Muscle morphology and intramuscular fat after treatment‐as‐usual including botulinum neurotoxin A injections in children with cerebral palsy

Developmental Medicine &Child Neurology, EarlyView.
Normalized muscle volume remained unchanged in all evaluated muscles after the 12‐month treatment‐as‐usual in children with cerebral palsy. Higher intramuscular fat fraction was observed in the medial gastrocnemius, suggesting concurrent intramuscular fat infiltration.

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 ...

The MacBrain Resource Center (MBRC) rhesus macaque postnatal brain histology datasets: Enabling new discoveries through NHP tissue and digital data Repositories

Journal of Anatomy, EarlyView.
The MacBrain Resource Center (MBRC) postnatal rhesus macaque brain histology datasets are organized into Collections that promote cost‐effective de novo research. This article provides examples from Collections 5, 6, and 7 and describes the histo‐ and immunohistochemical (IHC) processing of materials for Collection 6.

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 ...

High-angular resolution diffusion tensor imaging: physical foundation and geometric framework

Frontiers in Physics
This paper proposes a statistical physics-based data assimilation model for the mobility of water-bound hydrogen nuclear spins in the brain in the context of diffusion weighted magnetic resonance imaging (DWI or DW-MRI).

Collaborative Reconstruction of PROPELLER‐EPI Data Using POCSMUSE (CORPUSE) for High‐Fidelity Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1929-1946, October 2026.
ABSTRACT Purpose To develop a reconstruction framework for DW‐PROPELLER‐EPI that improves image quality and SNR efficiency under per‐blade acceleration while minimizing EPI‐related artifacts, enabling high‐resolution diffusion‐tensor imaging (DTI) with fewer blades.

Optimized Reduced Field of View and Fat Suppression Methods for Interleaved Multislice In Vivo Cardiac Diffusion Tensor Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1097-1110, September 2026.
ABSTRACT Purpose Slice interleaving, a limited phase encode (PE) field of view (FOV), and effective fat suppression are vital for efficient cardiac diffusion tensor imaging (cDTI) with minimal artifacts. This study aimed to optimize reduced FOV and fat suppression methods for interleaved multislice cDTI to improve signal‐to‐noise ratio (SNR) and ...

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 ...
