T1 accuracy for SMART₁Map, uncorrected MOLLI, and corrected MOLLI as a function of readout window duration T_acq (left) and heart rate (right). In both cases, although corrected MOLLI (red) shows improvement over uncorrected MOLLI (blue), it still tends toward underestimation, especially at low T1s. In general, T1 underestimation with MOLLI increases with T_acq, heart rate, and T1. In contrast, SMART₁Map (green) exhibits consistent accuracy across the range of T1s and demonstrates no sensitivity to T_acq or heart rate.
