Abstract

Nonalcoholic Fatty Liver Disease (NAFLD) is a clinical syndrome characterized by predominant macrovesicular steatosis of the liver. NAFLD comprises a range of liver conditions varying in severity of hepatocytes injury and resulting fibrosis-cirrhosis risk. Among these, hepatic steatosis (fatty liver) is referred to as NAFL, and nonalcoholic fatty liver (NAFL) is defined as a more grave process with both fat and inflammation in the liver that over time can cause liver cirrhosis (steatohepatitis). Liver biopsy is the gold standard method to differentiate, whether the patient with fatty liver has only steatosis, or NASH. Unfortunately, liver biopsy has well-known limitations (invasiveness and sampling variability) and cannot be proposed for all patients, especially given the high prevalence of NAFLD worldwide. This review discuss the radiologic evaluation of liver steatosis and fibrosis for patients with NAFLD.
