In patients with liver disease, MR elastography (MRE) is a non-invasive method for evaluating fibrosis. MRE is phase-based and sensitive to motion artefact, and is typically performed in end expiration. We found that navigator timed MRE shows no statistical difference to breath-held techniques for stiffness and reproducibility in 6 healthy volunteers, and may prove superior in patients unable to adequately hold their breath
