Core Tip
Core tip: Ultrasonography is a cost-effective imaging technique for the diagnosis of hepatic steatosis in clinical practice. Magnetic resonance spectroscopy and magnetic resonance imaging are the most accurate and reliable methods of quantifying liver fat, especially for longitudinal follow-up of patients with nonalcoholic fatty liver disease. Ultrasound elastography and magnetic resonance elastography are promising imaging methods to evaluate the degree of liver fibrosis and to differentiate nonalcoholic steatohepatitis from simple hepatic steatosis.
