One major challenge in submillimeter dMRI is the inherently low signal-to-noise ratio (SNR). to To address this issue, the simultaneous multislab (SMSlab) approaches were proposed but susceptible to slab boundary artifacts and require additional navigators for phase estimation. The gSlider sequences require relatively high RF power and peak amplitude, increasing SAR and complicating RF excitation. Here, we introduce a navigator-free approach called multishot-encoded simultaneous multi-slice (MUSIUM) imaging for enhanced SNR, low RF power and peak amplitude, and freedom from slab boundary artifacts.
