Figure 9

DENSE SNR of different flip angle strategies in two subjects at 3T. Spiral cine DENSE of a mid-ventricular slice was performed in two subjects with different flip angle strategies. The ramped flip angle strategies (dashed lines) ramp up to the indicated degree in the legend. Constant flip angle strategies (solid lines) provided high SNR in early systole at the expense of diastole. Ramped flip angle strategies (particularly 15°, 20°, and 25°) provided SNRs above 20 for most cardiac phases.
