2D GRE MRE liver images acquired at 4 transverse levels in breath-hold times >13s per slice is currently standard of care (SC_2D_4BH). The combination of wave polarity-inversion motion encoding and compressed-SENSE enables volumetric three-dimensional (3D) MRE data acquisition in a single breath-hold of <16 s, with identical spatial resolution and 5 slice equivalent coverage (3D_5Sl_SBH). In 19 participants, mean liver shear stiffness values estimated with SC_2D_4BH and 3D_5sl_SBH correlated very strongly (ICC=0.96) with a mean bias of 0.13 kPa (<5 %). 3D_5sl_SBH MRE provides similar stiffness estimates as SC_2D_4BH with increased coverage in a single breath-hold compared to 4 breath-holds.
