  1. * = P < 0.001 compared with ShMOLLI. † = P > 0.05 compared with MOLLI Low HR. ‡ = P < 0.001 compared with MOLLI Low HR. $Stress T1 data for MOLLI Low and High HR from extrapolated model-predicted dT1. Post-contrast T1 reflects the average T1 across each epoch, with statistical comparisons performed at N = 44 samples (based on the maximum number of MOLLI samples per epoch) to assure fair inter-method comparison.
