Unlike NAFL, NASH is characterized by intrahepatic inflammation, and is solely at risk of progression to cirrhosis and hepatocellular carcinoma (HCC). It is currently estimated that NAFLD affects approximately 25% of the world's adult population, and its incidence is rising in all regions of the world. Nevertheless, of all patients with NAFLD, only \~25% have NASH. Identifying patients with NASH is therefore crucial, determining the need for follow-up to detect the onset of fibrosis and/or HCC, and eventual access to therapeutic trials. Furthermore, intrahepatic inflammation, the initial driver of NASH, appears to play an important role in the development of fibrosis and HCC, which can occur in the absence of cirrhosis in thes
