Semiquantitative characterization of dynamic magnetic resonance perfusion of the liver in pediatric Fontan patients

Background Dynamic contrast-enhanced magnetic resonance imaging (MRI) of the liver in pediatric Fontan patients often shows peripheral reticular areas of hypoenhancement, which has not been studied in detail. Objective To semiquantitatively score the hepatic MR perfusion abnormality seen in pediatri...

Description
Summary:Background Dynamic contrast-enhanced magnetic resonance imaging (MRI) of the liver in pediatric Fontan patients often shows peripheral reticular areas of hypoenhancement, which has not been studied in detail. Objective To semiquantitatively score the hepatic MR perfusion abnormality seen in pediatric Fontan patients, and to correlate the perfusion abnormality with functional clinical and hemodynamic parameters.
