Improving quantitative susceptibility mapping for the identification of traumatic brain injury neurodegeneration at the individual level

Zeitschrift für Medizinische Physik
Background: Emerging evidence suggests that traumatic brain injury (TBI) is a major risk factor for developing neurodegenerative disease later in life.

Midbrain and pallidal iron changes identify patients with REM sleep behaviour disorder and Parkinson’s disease

npj Parkinson's Disease
Idiopathic REM sleep behaviour disorder (iRBD) is considered a prodromal form of Parkinson’s Disease (PD), potentially exhibiting similar patterns of neurodegeneration, such as brain iron changes.

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,

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 ...
