a inversion recovery for bright blood PSIR LGE in case with scar signal (blue) less than blood (red) resulting in poor contrast. b inversion recovery for Dark Blood (DB) PSIR using combined IR and T2 preparation to shift the null time of blood relative to the normal myocardium. In this case the delays are chosen such that the blood signal (red) is less than the myocardium (dashed gray) resulting in dark blood using PSIR reconstruction, which preserves the signal polarity. Inversion times to null the normal myocardium are depicted by vertical dashed lines. The loss in SNR due to the T2 preparation is mitigated by increased respiratory motion corrected averaging (MOCO)
