Using both quantitative susceptibility mapping (QSM) and diffusional kurtosis imaging (DKI) methods, we investigated age-related iron depositions in subcortical gray matters of globus pallidus (GP) and putamen (Pu). Besides, the contribution of iron deposition with aging to microstructural alterations in deep gray matter has also been studied by testing correlations between DKI parameters and susceptibility.
