Effects of Motion in Ultrashort Echo Time Quantitative Susceptibility Mapping for Musculoskeletal Imaging [PDF]
Journal of ImagingQuantitative susceptibility mapping (QSM) is a powerful magnetic resonance imaging (MRI) technique for assessing tissue composition in the human body. For imaging short-T2 tissues in the musculoskeletal (MSK) system, ultrashort echo time (UTE) imaging ...

Quantitative Susceptibility Mapping of Deep Grey Matter in MS: Association With Clinical Scores and Brain Volume Measures [PDF]
Brain and BehaviorBackground Changes in quantitative susceptibility mapping (QSM) of the deep grey matter (DGM) in multiple sclerosis (MS) are thought to reflect tissue damage invisible in conventional magnetic resonance imaging (MRI) sequences, such as iron‐related ...

MRI R2* and quantitative susceptibility mapping in brain tissue with extreme iron overload [PDF]
European Radiology ExperimentalBackground R2* and quantitative susceptibility mapping (QSM) are regarded as robust techniques for assessing iron content in the brain. While these techniques are established for normal or moderate iron levels, their usability in extreme iron overload ...

Incomplete spectrum QSM using support information
Frontiers in Neuroscience, 2023 IntroductionReconstructing a bounded object from incomplete k-space data is a well posed problem, and it was recently shown that this incomplete spectrum approach can be used to reconstruct undersampled MRI images with similar quality to compressed ...

Quantitative susceptibility mapping using plug-and-play alternating direction method of multipliers
Scientific Reports, 2022 Quantitative susceptibility mapping employs regularization to reduce artifacts, yet many recent denoisers are unavailable for reconstruction. We developed a plug-and-play approach to QSM reconstruction (PnP QSM) and show its flexibility using several ...
