Radial T1‐T2 sequence image acquisition, where t0, t1, …, t10 indicate the image acquisition time points, defined as the time when the 40th k‐space line is acquired, and dt1, dt2, …, dt10 are the durations between each acquisition time point, which are needed in the Bloch equation simulation for T1 and T2 calculation. ECG, electrocardiogram; and GRE, gradient echo
