Figure 5.
Distribution of iron in the subcortical nuclei reported by Hallgren and Sourander (1958, Fig. 1A), in relation to the average sample distribution of magnetic susceptibility values of the present study. The QSM data reflects means of susceptibility values in ppb, from 183 subjects (20-69 years). The values on the x axis reflects mg iron per 100 gram wet tissue, as reported in Table 1a, p. 43 in the work by Hallgren and Sourander (1958), from subjects aged 30-100 years, (r = .970, p = .000). The error bars represents standard deviations.
