Assessing robustness of quantitative susceptibility-based MRI radiomic features in patients with multiple sclerosis

Scientific Reports, 2023
Multiple Sclerosis (MS) is an autoimmune demyelinating disease characterised by changes in iron and myelin content. These biomarkers are detectable by Quantitative Susceptibility Mapping (QSM), an advanced Magnetic Resonance Imaging technique detecting ...

Retinal neurovascular alterations are associated with optic radiation microstructure in adrenomyeloneuropathy: A susceptibility separation MRI study

VIEW, EarlyView.
In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

Brain Susceptibility Changes in a Patient with Natalizumab-Related Progressive Multifocal Leukoencephalopathy: A Longitudinal Quantitative Susceptibility Mapping and Relaxometry Study [PDF]

, 2017
Brain MRI plays an essential role in both diagnosis and follow-up of the JC virus infection of the brain. Recently, MR studies with susceptibility-weighted imaging (SWI) sequences have shown hypointensities in U-fibers adjacent to white matter (WM ...

Harmonic field extension for QSM with reduced spatial coverage using physics-informed generative adversarial network

NeuroImage
Quantitative susceptibility mapping (QSM) is frequently employed in investigating brain iron related to brain development and diseases within deep gray matter (DGM). Nonetheless, the acquisition of whole-brain QSM data is time-intensive.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Separation of Diamagnetic and Paramagnetic Susceptibility Sources in Liver Using DECOMPOSE‐QSM

NMR in Biomedicine, Volume 39, Issue 12, December 2026.
Separating subvoxel paramagnetic and diamagnetic susceptibility sources in the liver enables noninvasive assessment of iron overload and fibrosis. Using DECOMPOSE‐QSM, we disentangle iron‐related paramagnetic effects from collagen‐related diamagnetic contributions within the same voxel.

Quantifying the Impact of Ocrelizumab on Paramagnetic Rim Lesions in Multiple Sclerosis

Annals of Clinical and Translational Neurology
Paramagnetic rim lesions (PRLs) are a subset of chronic active multiple sclerosis (MS) lesions marked by iron‐laden microglia and macrophages. Ocrelizumab, a monoclonal antibody targeting CD20+ B cells, suppresses acute MS activity, but its effect on ...
