Quantitative susceptibility mapping (QSM): Decoding MRI data for a tissue magnetic biomarker
In MRI, the main magnetic field polarizes the electron cloud of a molecule, generating a chemical shift for observer protons within the molecule and a magnetic susceptibility inhomogeneity field for observer protons outside the molecule. The number of water protons surrounding a molecule for detecting its magnetic susceptibility is vastly greater than the number of protons within the molecule f...
متن کاملIn Vivo Quantitative Susceptibility Mapping (QSM) in Alzheimer's Disease
BACKGROUND This study explores the magnetostatic properties of the Alzheimer's disease brain using a recently proposed, magnetic resonance imaging, postprocessed contrast mechanism. Quantitative susceptibility mapping (QSM) has the potential to monitor in vivo iron levels by reconstructing magnetic susceptibility sources from field perturbations. However, with phase data acquired at a single he...

متن کاملQuantitative susceptibility mapping (QSM) as a means to measure brain iron? A post mortem validation study
Quantitative susceptibility mapping (QSM) is a novel technique which allows determining the bulk magnetic susceptibility distribution of tissue in vivo from gradient echo magnetic resonance phase images. It is commonly assumed that paramagnetic iron is the predominant source of susceptibility variations in gray matter as many studies have reported a reasonable correlation of magnetic susceptibi...
متن کاملMeasurement of iron concentration in human brain using Quantitative Susceptibility Mapping (QSM): correlation with age
Introduction: Excessive iron deposition is often associated with neurodegenerative disorders, such as Parkinson’s disease (PD), Alzheimer’s disease and Huntington’s Chorea [1]. Quantitative measurement of regional iron deposition in the brain may help with diagnosis and assessment of disease progression. In order to use iron deposition as a new biomarker to stratify the stages of diseases, it i...
