FIG. 4.

Representative parameter maps of the center slice from the 64² reproducibility acquisition as evaluated by the standard model, and corresponding histograms for parameter distribution. The data in each panel corresponds to that displayed in the 128 × 128 data of Figure 3. As was the case in the 128² acquisition, similar parameter patterns and spatial distributions of high and low values are observed between scans. The corresponding histograms demonstrating the degree of parameter agreement are shown in the right column.
