We evaluated magnetic susceptibility of the brain in 202 neonates and infants. We manually placed volumes of interest of the caudate nucleus, globus pallidus, putamen and ventral posterior lateral nucleus of the thalamus in the MNI space. Our study showed that elevation of magnetic susceptibility probably associated with iron deposition of the basal ganglia and thalamus increased with chronological age from birth to 2 years using volume-of-interest analysis.
