Investigating the effect of masking and background field removal algorithms on the quality of QSM reconstructions using a realistic numerical head phantom

NeuroImage
Background field removal (BFR) is an important step in the Quantitative Susceptibility Mapping (QSM) pipeline, enabling the reconstruction of local susceptibility distributions by removing contributions from sources outside the region of interest (ROI ...

Quantitative susceptibility mapping for susceptibility source separation with adaptive relaxometric constant estimation (QSM-ARCS) from solely gradient-echo data

NeuroImage
To separate the contributions of paramagnetic and diamagnetic sources within a voxel, a magnetic susceptibility source separation method based solely on gradient-echo data has been developed. To measure the opposing susceptibility sources more accurately,

Susceptibility and diffusion MRI biomarkers predict development of Parkinsonism in iRBD

npj Parkinson's Disease
Quantitative MRI techniques, including quantitative susceptibility mapping (QSM) and diffusion tensor imaging (DTI), may detect early neurodegenerative changes in ɑ-synucleinopathies, especially within the midbrain.

Quantitative Susceptibility Mapping (QSM) Reconstruction from MRI Phase Data

, 2020
Quantitative susceptibility mapping (QSM) is a powerful technique that reveals changes in the underlying tissue susceptibility distribution. It can be used to measure the concentrations of iron and calcium in the brain both of which are linked with numerous neurodegenerative diseases.
