Systematic review protocol: Quantitative susceptibility mapping of brain iron accumulation in neurodegenerative diseases

Abstract

Iron has been found to play an important role in neurodegeneration. Quantitative susceptibility mapping (QSM) is a relatively new – and the most accurate - MRI technique available for assessment of iron deposition in the brain. There is a rapidly growing number of studies using QSM to investigate brain iron distribution in neurodegenerative diseases including but not limited to Alzheimer’s disease, Parkinson’s disease, Amyotrophic lateral sclerosis, Huntington disease and Wilson’s disease. These studies have shown increased iron deposition in the brain regions that are associated with the pathology of the disease. Additionally, QSM is found to be accurate in differential diagnosis of neurode..
