Magnetic Resonance Imaging of the Liver: Technical Considerations

Magnetic resonance imaging (MRI) is one the leading imaging modalities to evaluate liver diseases, with an active role both on focal liver lesions and diffuse parenchymal evaluation. Despite its diagnostic capabilities, MR imaging is far more difficult to manage than computed tomography (CT). The aim of the current chapter is to review the protocols for liver imaging using standard technical specifications able to provide reproducible image quality, and to review advanced applications encompassing quantification issues, allowing therapeutical monitoring and disease follow-up. The chapter also adresses strategies to derive functional information, especially using diffusion-weighted imaging and dedicated liver specific contrast agents. Its scope is to allow the reader an in-depth vision of modern MR of the liver from a clinical point of view, proposing imaging protocols effective at 1.5 and 3T magnets.
