While conventional MRE is easily performed during suspended respiration, a free breathing MRE technique would be advantageous in pediatric and other patients. We assessed the repeatability of free-breathing MRE in comparison to conventional breath held acquisitions in volunteers and the clinical performance of free-breathing MRE in a cohort of 56 patients with chronic liver diseases. Results demonstrated comparable repeatability and excellent agreement of the averaged liver stiffnesses measured using the two techniques. In summary, free-breathing MRE provides highly repeatable and accurate liver stiffness values.
