Figure 8


Fig. 3B —Bland-Altman plots. Difference ({Delta}) in LV ejection fraction (LVEF) between each pair—MDCT-derived LVEF and echocardiographically derived LVEF—is plotted against average value of sample pair (solid line = mean value of differences, dotted lines = mean value of differences ± 2 SD). Difference in LVEF does not vary in any systematic way over range of measurements. Mean difference is 3.3% ± 5.8% (range, -8.2% to 14.8%) to prejudice of average LVEF of echocardiography.
