THE ROLE OF RADIOLOGIC IMAGING IN THE DIAGNOSIS OF HEPATIC STEATOSIS
Hepatic steatosis is defined as excessive fat accumulation within the hepatocytes. It has a global prevalence of about 20–30% and an increase is recorded. Although steatosis is a potentially reversible process it may lead to serious complications, therefore, it is important to diagnose. The liver biopsy is currently considered as the gold-standard for diagnosing hepatic steanosis, even so it has several limitations, such as invasiveness and sampling variability. Excess fat accumulation also causes abnormal appearance of the liver parenchyma on radiological imaging such as ultrasonography, computed tomography and magnetic resonance imaging. The utility and limitation of each imaging modality for the diagnosis and quantification of hepatic steatosis will be overviewed in this article.
