Noninvasive diagnosis of nonalcoholic fatty liver disease, is the more expensive the better?

Nonalcoholic fatty liver disease (NAFLD) may be defined as a sexual dimorphic disease (1) featuring excess intrahepatic ectopic triglyceride deposition in patients who are free of competing etiologies of liver disease (2). NAFLD has a close, mutual and bi-directional relationship with metabolic syndrome (MetS), of which it may be either a cause (3) or an effect (4).
