Quantitative Susceptibility Mapping for Following Intracranial Hemorrhage [PDF]
Radiology, 2018 Purpose To follow the evolution of intracranial hemorrhage (ICH) by using quantitative susceptibility mapping (QSM). Materials and Methods Thirty-six patients with ICH confirmed at CT were enrolled to follow ICH evolution on day 2, 7, and 30 after symptom onset between August 2013 and April 2017.

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.

Quantitative susceptibility mapping of the midbrain in Parkinson's disease [PDF]
Movement Disorders, 2015 AbstractBackgroundParkinson's disease (PD) is marked pathologically by dopamine neuron loss and iron overload in the substantia nigra pars compacta. Midbrain iron content is reported to be increased in PD based on magnetic resonance imaging (MRI) R2* changes.

Value of Quantitative Susceptibility Mapping in Clinical Neuroradiology
Journal of Magnetic Resonance Imaging, 2023 Quantitative 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.

Rapid multi-orientation quantitative susceptibility mapping [PDF]
NeuroImage, 2016 Three-dimensional gradient echo (GRE) is the main workhorse sequence used for susceptibility weighted imaging (SWI), quantitative susceptibility mapping (QSM), and susceptibility tensor imaging (STI). Achieving optimal phase signal-to-noise ratio requires late echo times, thus necessitating a long repetition time (TR).
