Figure 2

Performance of SMART1Map (left), MOLLI (middle) and SASHA (right) at 60 and 100 bpm showing a) average accuracy of mean T1s over each of the 22 ROIs, b) repeatability of mean T1s over 10 repeats, and c) pixel-wise variability of measured T1 values within each sample. All data are reported as a percentage of reference T1 values from IR-spin echo. Data are shown for 4 cases: i) averaged across all T1s (black line); ii) T1 < 700 ms (red, typical of post-contrast myocardium); iii) 700 < Y1 < 1200 ms (green); and iv) T1>1200 ms (blue, typical of native myocardium).
