MR thermometry using dual-echo single-shot EPI was evaluated in a phantom. Dual-echo EPI resulted in better temperature stabilities than the single echo acquisitions. This sequence was successfully combined with SMS, which also resulted in higher temperature stability than the single echo acquisitions.
