Weak‐harmonic regularization for quantitative susceptibility mapping [PDF]

open access: yesMagnetic Resonance in Medicine, 2018
PurposeBackground‐field removal is a crucial preprocessing step for quantitative susceptibility mapping (QSM). Remnants from this step often contaminate the estimated local field, which in turn leads to erroneous tissue‐susceptibility reconstructions.

Quantitative Susceptibility Mapping for Following Intracranial Hemorrhage [PDF]

open access: yesRadiology, 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.

Rapid multi-orientation quantitative susceptibility mapping [PDF]

open access: yesNeuroImage, 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).

Tissue magnetic susceptibility mapping as a marker of tau pathology in Alzheimer's disease. [PDF]

open access: yes, 2017
Alzheimer's disease is connected to a number of other neurodegenerative conditions, known collectively as 'tauopathies', by the presence of aggregated tau protein in the brain.

Brain Nucleus Changes in Cognitive Disorders: Examining By the Quantitative Susceptibility Mapping (QSM) Technique [PDF]

open access: yesIranian Journal of Medical Physics
Introduction: Iron deposition is vital for damaging neurons and causing different cognitive disorders. Today, using the quantitative susceptibility mapping (QSM) technique, iron deposits in other brain areas can be assessed and measured. This study aimed
