  1. Color coding is in accordance with excellent [Bold], good [Italic], poor [Undeline] scores for ICCs and Dice coefficients (ICC: 0.90–1.00 [excellent], 0.75–0.89 [good], 0.00–0.74 [poor]; Dice coefficients: 0.70–1.00 [excellent], 0.50–.69 [good], 0–0.49 [poor]). We have also highlighted regions with > 1% bias as a portion of a volume’s structure in Italic
