Region of interest (ROI) susceptibility values measured at both 3T and
7T and both 5 and 10 echoes (5E and 10E) averaged across the 10 subjects.
Susceptibility is expressed in parts per billion (ppb). The selected ROIs are
Caudate Nucleus (CN), Putamen (PU), Globus Pallidus (GP), Substantia Nigra (SN),
Red Nucleus (RN), Splenium of Corpus Callosum (SCC) and Dentate Nucleus
(DN).
