Table 1.

This table lists the percent improvement in signal loss recovery and B1+ homogeneity for the five-rung and three-rung 4D spectral-spatial pulses over the standard pulse (averaged across all ROI’s for all slices in each subject). The p-values reflect the significance of the results compared to the standard pulse.
