Abstract

Liver imaging is now essential for detecting and characterizing focal and diffuse liver lesions, including the assessment of chronic liver disease and certain acute conditions affecting the liver and the biliary ducts. In this article, we illustrate the role of MRI in the study of the liver and biliary tree. The use of contrast media and the ongoing development of new sequences are continuously improving the diagnostic performance of hepatobiliary MRI, which permits a comprehensive evaluation of the liver and biliary tract. The reproducibility, safety, and tissue characterization capabilities are the key advantages of MRI compared to ultrasound and computed tomography, while the relatively long examination times and the potential for artifacts are the main limitations. In this article, primary and secondary liver focal lesions within cirrhotic and non-cirrhotic liver are discussed separately; signal intensity (SI) and enhancement characteristics of benign and malignant liver lesions are described in the text and summarized in tables. A separate section is dedicated to the assessment of the intra- and extrahepatic biliary ducts and related common diseases.
