  4. 2. Non-Invasive Characterization of Liver Disease : By Multimodal Quantitative Magnetic Resonance

    Author : Markus Karlsson; Peter Lundberg; Gunnar Cedersund; Nils Dahlström; Stergios Kechagias; Steven Sourbron; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : There is a large and unmet need for diagnostic tool that can be used to characterize chronic liver diseases (CLD). In the earlier stages of CLD, much of the diagnostics involves performing biopsies, which are evaluated by a histopathologist for the presence of e.g. fat, iron, inflammation, and fibrosis.
