Liver fat quantification: when do we need it?

In recent years the most rapidly emerging disease in general hepatology is the Metabolic dysfunction-Associated Fatty Liver Disease (MAFLD). This a new definition, which was suggested to replace and extend what was previously known as Non Alcoholic Fatty Liver Disease (NAFLD) and Non Alcoholic Steatohepatitis (NASH). The new proposal of MAFLD was set forward because the criterion for diagnosing NAFLD/NASH requires absence of any other chronic liver condition (e. g. viral hepatitis, immune-related cholestatic liver disease, etc) and absence of any over threshold intake of alcohol.
