Evaluation of the Reproducibility of the Measurement of the QSM Signal (Quantitative Susceptibility Mapping)

Many central nervous system pathologies have an inflammatory component, often associated with an accumulation of disability and more severe tissue damage. In multiple sclerosis, the inflammatory process is in part characterized by the activation of microglia, an entity of the innate inflammatory system, as well as a breakdown of the blood-brain barrier. During inflammation, activated microglia may contain high levels of iron, characterizing its activated state.
