SMART1Map sequence was performed on 6 phantoms with different T1 values. Sixteen schemes were prescribed: 4 heart rates (60, 80, 100, 120 bpm), 2 spatial resolutions (FOV = 30 cm and FOV = 48 cm) and 2 cardiac phases (systole and diastole). The results show that SMART1Map underestimates long T1 (native T1 myocardium) at any scheme. We also found an increase in error with reduced FOV (all other parameters being identical), and an influence of the cardiac phases on T1 at the levels of native and post-contrast blood and myocardium
