Synopsis

Keywords: Body: Liver, Contrast mechanisms: Diffusion, Contrast mechanisms: Elastography

Cirrhosis is the most important risk factor for hepatocellular carcinoma; therefore, it is important to accurately assess advanced fibrosis. Liver biopsy remains the gold standard for diagnostic evaluation of hepatic fibrosis. However, its invasive nature and high cost make it difficult to perform repeatedly. MRI is a noninvasive imaging tool that can evaluate hepatic fibrosis. There are several methods to assess hepatic fibrosis on MRI. This talk will provide an overview of diagnostic methods for hepatic fibrosis by MRI including uptake of gadoxetic acid, T1 mapping, diffusion-weighted imaging including intravoxel incoherent motion, T1rho, radiomics/ artificial intelligence, and MR elastography.
