We studied several ways to optimize efficiency of CRI at both 1.5 and 3T. We showed (for 3T case) that the CRI efficiency may be improved by including extra sample(s) from low &#916; range (<1 kHz). Further, we demonstrated that SAR-efficient pulses may provide additional large efficiency gains in CRI. At the same time, high BW SAR-efficient pulses may lead to a significant error in qMT measures for the low offset frequency designs. One simple solution is to resort to longer SAR-efficient pulses.
