Relationship of MR elastography determined liver stiffness with cardiac function after Fontan palliation.

Purpose: To use MR elastography to assess liver stiffness in patients with congenital heart disease palliated with the Fontan procedure and correlate findings with cardiac index and other functional parameters obtained during cardiac MRI.

Materials And Methods: We performed a retrospective study of 14 patients (15 examinations) with Fontan circulation who underwent both cardiac MRI and liver MR elastography (MRE) on the same day. Liver stiffness was determined by calculating the mean liver stiffness from four slice locations.
