Usefulness of Gadolinium Ethoxybenzyl Diethylenetriamine Pentaacetic Acid–Enhanced Magnetic Resonance Imaging for the Evaluation of Hepatic Functional Reserve

Background To determine the usefulness of enhanced rate gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid–enhanced magnetic resonance imaging (EOB-MRI) during hepatobiliary phase as a new parameter for hepatic functional reserve. Aim We retrospectively analyzed 153 patients who underwent EOB-MRI before radiofrequency ablation or resection between January 2008 and December 2012. The was estimated using ratio regions interest in liver parenchyma to that paraspinal muscles. examined along with function tests fibrosis levels any correlations. Results A high correlation found indocyanine green retention at 15 minutes (r = −0.66, P < 0.0001). Additionally, moderate discovered serum albumin 0.57, 0.0001), level −0.48, also weakly correlated platelet count 0.28, 0.0005), aspartate aminotransferase −0.37, total bilirubin −0.26, 0.0014), prothrombin activity 0.27, 0.0014). Conclusions EOB-MRI–enhanced strongly correlates
