msQSM: Morphology-based self-supervised deep learning for quantitative susceptibility mapping

NeuroImage, 2023
Quantitative susceptibility mapping (QSM) has been applied to the measurement of iron deposition and the auxiliary diagnosis of neurodegenerative disease. There still exists a dipole inversion problem in QSM reconstruction.

Tissue magnetic susceptibility mapping as a marker of tau pathology in Alzheimer's disease. [PDF]

, 2017
Alzheimer's disease is connected to a number of other neurodegenerative conditions, known collectively as 'tauopathies', by the presence of aggregated tau protein in the brain.

Mapping genetic determinants of host susceptibility to Pseudomonas aeruginosa lung infection in mice. [PDF]

, 2016
Background: P. aeruginosa is one of the top three causes of opportunistic human bacterial infections. The remarkable variability in the clinical outcomes of this infection is thought to be associated with genetic predisposition.

Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds. [PDF]

, 2015
BackgroundA key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool ...

Imaging the Centromedian Thalamic Nucleus Using Quantitative Susceptibility Mapping

Frontiers in Human Neuroscience, 2020
The centromedian (CM) nucleus is an intralaminar thalamic nucleus that is considered as a potentially effective target of deep brain stimulation (DBS) and ablative surgeries for the treatment of multiple neurological and psychiatric disorders.

Quantitative Susceptibility Mapping Reveals an Association between Brain Iron Load and Depression Severity

Frontiers in Human Neuroscience, 2017
Previous studies have detected abnormal serum ferritin levels in patients with depression; however, the results have been inconsistent. This study used quantitative susceptibility mapping (QSM) for the first time to examine brain iron concentration in ...

Simultaneous Quantitative Susceptibility Mapping of Articular Cartilage and Cortical Bone of Human Knee Joint Using Ultrashort Echo Time Sequences

Frontiers in Endocrinology, 2022
BackgroundIt is of great clinical importance to assess the microstructure of the articular cartilage and cortical bone of the human knee joint. While quantitative susceptibility mapping (QSM) is a promising tool for investigating the knee joint, however,

Weak‐harmonic regularization for quantitative susceptibility mapping [PDF]

Magnetic Resonance in Medicine, 2018
PurposeBackground‐field removal is a crucial preprocessing step for quantitative susceptibility mapping (QSM). Remnants from this step often contaminate the estimated local field, which in turn leads to erroneous tissue‐susceptibility reconstructions.

Quantitative susceptibility mapping in ischemic stroke patients after successful recanalization

Scientific Reports, 2021
Quantitative susceptibility mapping (QSM) is a novel processing method for gradient-echo magnetic resonance imaging (MRI). Higher magnetic susceptibility in cortical veins have been observed on susceptibility maps in the ischemic hemisphere of stroke ...
