From: T1-mapping in the heart: accuracy and precision

Figure 6

Simulated off-resonance response of MOLLI for 5s(3s)3s protocol with TR = 2.8 ms using FA = 35 (left) and 25 (right) at various T1’s for myocardial T2 = 45 ms. Using a lower flip angle (FA) trades SNR (precision) for improved accuracy and reduced off-resonance sensitivity. For T1 = 1000 ms, sensitivity to off-resonance over ±100 Hz is 40 ms and 25 ms for FA = 35° and 20°, respectively.
