Abbreviated Liver Magnetic Resonance Imaging Protocols and Applications

Abstract

Abbreviated magnetic resonance imaging (AMRI) approach became a hot topic in liver imaging recently. Different AMRI protocols including noncontrast AMRI (NC-AMRI), hepatobiliary-AMRI (HBP-AMRI) using gadoxetic acid, and dynamic-AMRI (Dyn-AMRI) using extracellular contrast agent, have been described in the literature. In this review, the use of these AMRI approaches in various indications including hepatocellular carcinoma (HCC) screening and surveillance in chronic liver disease; fat, iron, and fibrosis screening and assessment in nonalcoholic fatty liver disease (NAFLD); and finally liver metastasis screening and surveillance in patients with colorectal cancer are summarized.
