Bullseye plots comparing the native T1-times (top row), precision (middle row) and the ECV-values (bottom row) of the three T1-mapping sequences averaged over all volunteers. The given ECV-values were calculated from post-contrast T1 acquired 15 min after GBCA injection. Segmentation was performed according to the AHA 16-segment model in three short-axis slices (A = apical, M = mid-ventricular, B = basal). The average across all segments is given in the center of the bullseye, the slice averages can be found below. The MOLLI sequence shows lower T1, better precision and higher ECV-values compared to the saturation-recovery methods. SAPPHIRE results show similar native T1- and ECV-values with slightly better precision compared with SASHA
