Bland–Altman plots for intra-observer and inter-observer reproducibility of T1 mapping. Bias (solid lines) and 95% limits of agreement (dashed lines) are shown. The first row shows the intra-observer reproducibility of T1 base (A), T1 middle (B), T1 apex (C), and T1 global (D). The second row shows the inter-observer reproducibility of T1 base (E), T1 middle (F), T1 apex (G), and T1 global (H)
