Value of Quantitative Susceptibility Mapping in Clinical Neuroradiology
Journal of Magnetic Resonance Imaging, 2023Quantitative susceptibility mapping (QSM) is a unique technique for providing quantitative information on tissue magnetic susceptibility using phase image data. QSM can provide valuable information regarding physiological and pathological processes such as iron deposition, hemorrhage, calcification, and myelin.

Image Reconstruction in Quantitative Susceptibility Mapping
SIAM Journal on Imaging Sciences, 2016Summary: This paper deals with a reconstruction problem in magnetic resonance imaging where the Fourier transform of the sought-for object can't be obtained in the vicinity of a cone-shaped surface. This leads to streak-shaped artifacts in the sagittal views of the object.

A Method of Reduction of Artifacts of Quantitative Susceptibility Mapping
SIAM Journal on Imaging Sciences, 2016The author points out the problem of spurious artifacts encountered in standard approaches of solving the inverse problem for the local magnetic susceptibility mapping typical in medical scanner applications. A new well posed analytical method based on the Radon transform is shown to reduce the number of artifacts in recovering the magnetic ...

Rapid quantitative susceptibility mapping of intracerebral hemorrhage
Journal of Magnetic Resonance Imaging, 2019BackgroundQuantitative susceptibility mapping (QSM) offers a means to track iron evolution in hemorrhage. However, standard QSM sequences have long acquisition times and are prone to motion artifact in hemorrhagic patients.PurposeTo minimize motion artifact and acquisition time by performing rapid QSM in intracerebral hemorrhage (ICH) using single‐shot

Sparse methods for Quantitative Susceptibility Mapping
SPIE Proceedings, 2015Quantitative Susceptibility Mapping (QSM) aims to estimate the tissue susceptibility distribution that gives rise to subtle changes in the main magnetic field, which are captured by the image phase in a gradient echo (GRE) experiment. The underlying susceptibility distribution is related to the acquired tissue phase through an ill-posed linear system ...

Quantitative trait locus mapping for atherosclerosis susceptibility
Current Opinion in Lipidology, 2003Atherosclerosis is a complex trait with both environmental and genetic aspects. Although some progress has been made in defining genes associated with atherosclerosis in humans, animal models have been useful in learning about pathways and genes involved in atherogenesis.
