Bland-Altman plots demonstrating the reproducibility of the proportion of the LA shell occupied by post ablation atrial scar (PAAS), comparing scan acquisitions performed at the same time points post gadolinium administration. The top left chart shows the comparison for acquisitions performed with identical imaging parameters (‘Repro’). The other three charts show the reproducibility for those performed with differing imaging protocols, as previously detailed. Crosses show data points for comparison of acquisitions at 10 min post gadolinium (C1,4), open circles for comparison of acquisitions at 20 min post gadolinium (C2,5), and closed circles for comparison of acquisitions at 30 min post gadolinium (C3,6). Red lines show mean bias ±95% confidence interval
