Inverse Problem in Quantitative Susceptibility Mapping
SIAM Journal on Imaging Sciences, 2014Quantitative susceptibility mapping (QSM) is a new medical imaging technique that can visualize magnetic susceptibility, changes of which in tissue indicate various disease processes involving iron transport. The inverse problem of QSM is to recover the susceptibility distribution of the human body from the measured local field that is expressed by the

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 ...

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

Image Reconstruction in Quantitative Susceptibility Mapping
SIAM Journal on Imaging Sciences, 2016This 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. We describe a method for reducing theses artifacts by analytical continuation. We present

To clarify the temperature dependence of susceptibility estimated by quantitative susceptibility mapping (QSM) analysis, we investigated the relationship between temperature and susceptibility using a cylinder phantom with varying temperatures. Six solutions with various concentrations of superparamagnetic iron oxide (SPIO) nanoparticles were employed.

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.
