This study explores, with relatively unbiased methods,
the relationship between increased paramagnetism in
brain parenchyma and age. Brain magnetostatics was
probed with quantitative susceptibility mapping (QSM)
revealing strong striatal effects as a function of age.
In addition, QSM clusters in the diencephalon,
mesencephalonand in a more patchy distribution, across
the cerebral cortex and posterior white matteralso
emerged as age-related effects.
