Regression analysis and assessment of mean differences between EF and indexed SV between acquisitions. A: linear regression analysis of CINE Seg-IR versus CINE Seg for EF B: linear regression analysis of CINE Seg-IR versus CINE Seg for BSA indexed SV C: Bland-Altman plot comparing CINE Seg-IR and CINE Seg EF D: Bland-Altman plot comparing CINE Seg-IR and CINE Seg BSA indexed SV. Red points indicate averages outside of 1.96 SD. CINE Seg-IR = segmented sparsely sampled tPAT factor 4 acceleration with iterative SENSE reconstruction using L1-regularization; CINE Seg = conventional segmented cine SSFP sequence with GRAPPA factor 2 acceleration; EF = ejection fraction; SV = stroke volume
