(A) Absolute fat fraction difference (top) and cross-sectional area (CSA) fat fraction difference (bottom) for each individual muscle for the scan-rescan (red, n = 26), interobserver (blue, n = 3), and intraobserver (green, n = 3) volume variability (B) Bland–Altman plots for scan-rescan (red, left), interobserver (blue, middle), and intraobserver (green, right) volumetric fat fraction difference. (C) Comparison of muscle labels from overall raw label (outline) and an eroded version of the label (filled) for the 26 KKI scan-rescan cases. Correlation of the difference in raw fat fraction difference (%) and eroded muscle fat fraction difference (%) for all complete coverage muscle. The linear regression line is shown in black (y = 1.03*x + 0.02). (D) Correlation between the clinical fat rating and fat fraction found for all Wellstone patients with complete coverage muscles.
