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 …

Quantitative susceptibility mapping (QSM) has enabled magnetic resonance imaging (MRI)
of tissue magnetic susceptibility to advance from simple qualitative detection of hypointense …

Disruption of iron homeostasis as a consequence of aging is thought to cause iron levels to
increase, potentially promoting oxidative cellular damage. Therefore, understanding how …

Quantitative susceptibility mapping (QSM) is a recently developed magnetic resonance
imaging (MRI) technique for quantifying the spatial distribution of magnetic susceptibility …

Myelin loss and iron accumulation are cardinal features of aging and various
neurodegenerative diseases. Oligodendrocytes incorporate iron as a metabolic substrate for …

Quantitative susceptibility mapping (QSM) is an MR technique that depicts and quantifies
magnetic susceptibility sources. Mapping iron, the dominant susceptibility source in the …

Object This study evaluates inter-site and intra-site reproducibility at ten different 7 T sites for
quantitative brain imaging. Material and Methods Two subjects–termed the “traveling heads” …

Abstract Quantitative Susceptibility Mapping (QSM), best known as a surrogate for tissue
iron content, is becoming a highly relevant MRI contrast for monitoring cellular and vascular …

Age and sex can influence brain iron levels. We studied the influence of these variables on
deep gray matter magnetic susceptibilities. In 183 healthy volunteers (44.7±14.2 years …

Purpose To assess the reproducibility of brain quantitative susceptibility mapping (QSM) in
healthy subjects and in patients with multiple sclerosis (MS) on 1.5 and 3T scanners from …
