MR Elastography of the Liver: Observations from a Review of 1,377 Exams

A retrospective review of 1,377 clinical hepatic MRE examinations was performed. The technical success rate in this broad spectrum of patients was over 94%. The analysis also indicated that MRE-assessed hepatic stiffness correlates with many histological and physiological parameters besides the well-established fibrosis extent, including blood pressure and serum liver enzyme tests. The use of MRE to assess changes in tissue mechanics associated with these parameters could provide new insights into the natural history of hepatic diseases and may have significant diagnostic value in the future.
