Fig. 4

Bland–Altman plots of the average volume difference estimation across Scan 1, Scan 2, and Scan 3 for the left Lateral Nucleus (dark blue) and right Medial Nucleus (light blue). The horizontal axis indicates the average difference in Bland–Altman “bias” (difference between subregional volume output for different scans, as a proportion of a region’s volume), while the vertical axis indicates the number of scans with a given value. Of note, the left Lateral Nucleus has a low degree of bias (as a proportion of the region’s volumes; 0.108%), while the right Medial Nucleus has a fair degree of bias (1.047%)
