Clinically, motion occurring between breath-hold acquisitions during a magnetic resonance elastography (MRE) scan is assumed negligible and therefore not corrected. In this work, we demonstrate through simulations on a phantom that motion of this degree does impact elasticity reconstruction, which highlights the need for care to be taken to account for this motion.
