Free-breathing acquisition of pancreatic MR elastography can potentially introduce errors in stiffness reconstruction. In this study, breathing tasks are introduced during interleaved and reversed slice order MRE acquisition to determine if the quality of MRE increases. The shear-wave speed and octahedral shear strain signal-to-noise-ratio in the pancreas did not significantly change when using breathing tasks. However, the stability of the pancreas location over time increases when using breathing tasks combined with reversed slice ordering as well as the octahedral shear strain signal-to-noise-ratio in the whole abdomen. Future research should focus on comparing shear-wave speed reproducibility of both MRE methods.
