Paramagnetic susceptibility

1. Age increases paramagnetic susceptibility in humans.

   “Consistent with in vivo analyses, the putamen's paramagnetic and total QSM susceptibility values demonstrated a strong age association in our postmortem condition, and it was the only region in which susceptibility values increased linearly with age.”

1. Iron is associated with paramagnetic susceptibility in humans.

   “Finally, the analysis of ex vivo putamen tissue samples revealed a moderate association between paramagnetic susceptibility and iron concentration, supporting iron's biological contribution to MRI paramagnetic susceptibility maps of the putamen.”
