Non-invasive Evaluation of Liver Fibrosis, Steatosis, and Nonalcoholic Steatohepatitis in Biopsy-Proven NAFLD Patients

As nonalcoholic fatty liver disease (NAFLD) is becoming a leading cause of chronic liver disease, non-invasive diagnosis of disease severity in NAFLD is urgently needed. In this study, the investigators compared hepatic fibrosis and steatosis using MR imaging and transient elastography (TE) and tried to find non-invasive diagnostic marker for NASH and advanced fibrosis. This is a multicenter prospective study of patients with biopsy-proven NAFLD. The patients were underwent laboratory test, liver biopsy, MRI and TE within 6 months of enrollment. MRI examination included MR spectroscopy (MRS), and MR elastography (MRE). TE measured liver stiffness and controlled attenuation parameter (CAP).
