All the previous test-retest human liver MRE studies could involve physiological stiffness change . In this study, our goal was to evaluate MRE test-retest repeatability with liver phantoms to avoid the possible influence of physiological changes in humans. We hypothesized that the variations of test-retest MRE stiffness measurements of phantoms were smaller than that of human livers.
