OBJECTIVE. The inflammatory subtype of nonalcoholic fatty liver disease, nonalco- holic steatohepatitis, is becoming one of the most important causes of chronic liver disease. In this article, we discuss the epidemiology, pathogenesis, and clinical and radiologic diagno- sis of the subtypes of nonalcoholic fatty liver disease.
CONCLUSION. We discuss the current and evolving imaging tests in the evaluation of hepatic fatty content, inflammation, and fibrosis.
