Figure 5.

R2^* in the same selected iron‐rich nuclei as shown in Fig. 4. PU: putamen; GP: globus pallidus. CN: caudate nucleus; SN; substantia nigra; RN: red nucleus; DN: dentate nucleus. The R2^* values of these nuclei were fitted with the exponential model [Eq. (4)]. The fitted equations are listed in Table 2, and the fitted curves are plotted as solid lines (including both male and female). The dashed and dotted lines represent the functional and observation bounds of 95% confidence. Open circles: male, closed circles: female.
