Core Tip
Core tip: Noninvasive methods used to diagnosis nonalcoholic fatty-liver disease (NAFLD) include ultrasonography (US), computed tomography, and magnetic resonance imaging. Although these methods are reliable for the noninvasive detection of moderate to severe fatty changes in the liver, they are not reliable for detecting nonalcoholic steatohepatitis and fibrosis. New imaging technologies, such as US-based transient elastography, acoustic radiation force impulse and magnetic resonance-based elastography, may be used to determine the severity of liver fibrosis. Liver scintigraphy has recently been proposed to evaluate the diagnosis of nonalcoholic steatohepatitis, and has potential for the evaluation of patients with NAFLD.
