Inverse Problem in Quantitative Susceptibility Mapping

SIAM Journal on Imaging Sciences, 2014
Summary: Quantitative 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 ...

Quantitative susceptibility mapping evaluation of glioma

European Radiology, 2023
To comprehensively evaluate the glioma using quantitative susceptibility mapping (QSM).Forty-two patients (18 women; mean age, 45 years) with pathologically confirmed gliomas were retrospectively included. All the patients underwent conventional and advanced MRI examinations (QSM, DWI, MRS, etc.).

Reducing Streaking Artifacts in Quantitative Susceptibility Mapping [PDF]

SIAM Journal on Imaging Sciences, 2017
It is well-known that reconstruction algorithms in quantitative susceptibility mapping often contain streaking artifacts. In [1], the cause of the artifacts is identified as propagation of singularities. In this work, we analyze such singularities carefully and propose some strategies to reduce the artifacts.

Overview of quantitative susceptibility mapping

NMR in Biomedicine, 2016
Magnetic susceptibility describes the magnetizability of a material to an applied magnetic field and represents an important parameter in the field of MRI. With the recently introduced method of quantitative susceptibility mapping (QSM) and its conceptual extension to susceptibility tensor imaging (STI), the non‐invasive assessment of this important ...
