Effect of B0 and B1 variations on T2 estimation using simulation of Bloch equation. Nominal myocardium T1 and T2 values (1200 ms and 50 ms respectively) were used during simulation. The error is reported as the difference between the estimated T2 value and the true T2 value (50 ms). (a) Normalized longitudinal magnetization directly after applying the T2prep pulse, (b) Error in T2 estimation, relative to the used reference T2 value using 2-parameter fit, (c) using 2-parameter fit and the proposed compensation of 90°,-90° pulses for TET2P = 0, (d) using 3-parameter fit, and (e) using 3-parameter fit and the proposed compensation of 90°,-90° pulses for TET2P = 0.
