Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

open access: yesAnnals of Neurology, Volume 100, Issue 2, Page 295-304, August 2026.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

Glymphatic Dysfunction in Children With Type 2 and 3 Spinal Muscular Atrophy

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
This study reveals glymphatic dysfunction in children with spinal muscular atrophy (SMA), characterized by increased cerebrospinal fluid volume and reduced ALPS index. These alterations correlate with clinical severity, identifying glymphatic dysfunction as a previously unrecognized feature of SMA pathophysiology.

Multimodel Diffusion MRI Signatures in Atypical Parkinsonian Disorders

open access: yesHuman Brain Mapping, Volume 47, Issue 11, 01 August 2026.
We implemented a diffusion MRI framework to analyze clinically compatible multishell data across 123 participants, including controls, Parkinson's disease (PD), corticobasal syndrome (CBS), and progressive supranuclear palsy Richardson's syndrome (PSP‐RS). Diffusion models included DTI, free‐water elimination (FWE), NODDI, and fixel‐based analysis (FBA)

Cross‐Vendor Validation of Proton Density Fat Fraction and T1 Mapping Using a Combined Proton Density Fat Fraction—T1 Phantom

open access: yesJournal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 482-492, August 2026.
ABSTRACT Background In chronic liver disease, fat and fibroinflammatory changes often coexist. However, their biomarkers, proton density fat fraction (PDFF) and T1, are typically assessed separately. Their reproducibility under mutual confounding remains unclear.
