Figure 5 Comparisons Between RT3DE and CMR Measurements of LV Volumes and EF

These plots show the results of linear regression and Bland-Altman analyses between RT3DE-derived LV volumes (end-diastolic volume [EDV] and end-systolic volume [ESV]) and ejection fraction (EF) against CMR reference values obtained in 92 study patients: r values and difference from CMR values averaged over patients (bias) ± standard deviation (95% limits of agreement [LOA]). Despite the high correlations that were similar to previously published single-center studies, RT3DE-derived volumes showed large negative biases in the multicenter setting.
