Multimodality Screening of Hepatic Nodules in Patients With Congenital Heart Disease After Fontan Procedure: Role of Ultrasound, ARFI Elastography, CT, and MRI

摘要

OBJECTIVE. Currently, there is no consensus in the literature regarding the screening of hepatic nodules in patients who have undergone the Fontan procedure. The objectives of this study are to evaluate in this population the frequency of hepatic nodules at ultrasound (US), CT, and MRI; to measure liver stiffness using acoustic radiation force impulse (ARFI) elastography; and to investigate predictive factors for hepatic nodules.
