Quantitative Susceptibility Mapping of the Cervical Spinal Cord at 3T and Application to Multiple Sclerosis. [PDF]
NMR BiomedWe adapted to the spinal cord (SC) an MRI technique called quantitative susceptibility mapping (QSM) to produce the first high‐resolution axial QSM maps of the cervical SC. Applied to multiple sclerosis, it reveals differences between gray matter, white matter, and lesions, suggesting its potential for improved lesion characterization.

Reducing Variability in Deep Gray Matter QSM Using Differential ROI Referencing: A Phantom and In Vivo Evaluation. [PDF]
NMR BiomedDifferential ROI referencing in QSM reduces subject‐specific offsets and improves group‐discrimination sensitivity, enabling detection of PD‐related susceptibility differences (SN–PU). ABSTRACT Quantitative susceptibility mapping (QSM) measures the intrinsic magnetic susceptibility of tissues.

Prediction of early neurological deterioration using quantitative susceptibility mapping in small artery occlusion ischemic stroke. [PDF]
IBRO Neurosci RepBackground: Approximately 20–30% of ischemic stroke patients with small artery occlusion (SAO) experience early neurological deterioration (END) after stroke onset, which is associated with a poor prognosis.

Evidence of Iron Accumulation in Cerebral Adrenoleukodystrophy: A Potential Novel Disease Mechanism. [PDF]
Ann Clin Transl NeurolABSTRACT In this first application of Quantitative Susceptibility Mapping Source Separation to cerebral adrenoleukodystrophy, we uncovered alterations in iron and myelin within lesions and normal appearing white matter. As validation, we demonstrate abnormal iron accumulation in those same compartments within primary brain tissue.

Bidirectional genetic and phenotypic links between smoking and striatal iron content involving dopaminergic and inflammatory pathways. [PDF]
AddictionAbstract Background and aims Tobacco smoking is a major risk factor for cardiovascular and lung diseases. A better understanding of its neurobiological underpinnings will benefit the prevention of smoking‐related illnesses and mortality. Previous studies link smoking to increased iron concentration in the striatum, a central component of the brain's ...
