About

The main objective is to compare the accuracy of transient elastography taking into account liver steatosis determined by MRI, to liver biopsy for the diagnosis of liver fibrosis ≥F2 in patient with NAFLD.

Full description

No alcoholic fatty liver disease (NAFLD) is induced by an abnormal build up of fat in the liver. It can induce liver damage, namely fibrosis, which leads to cirrhosis and an increased risk of liver cancer. The diagnosis of liver fibrosis is thus critical to identify patients at risk.

Liver biopsy is the gold standard for the diagnosis of liver fibrosis. However this invasive test is expensive and has a significant morbidity.

To avoid this others non invasive test have been developed to assess steatosis and fibrosis of the liver :

  • Magnetic Resonance Imaging can quantify liver steatosis accurately.
  • Transient elastography (Fibroscan®) is approved for the diagnosis of fibrosis in chronic hepatitis C. However results in NAFLD were disappointing. Further, steatosis by heightening liver elasticity is thought to be the cause of these poor results.
  • Several biological tests or score are also approved in chronic hepatitis C, but not in NAFLD.

The hypothesis driving this study is that by accounting for liver steatosis through the mean of MRI, we could more accurately interpret transient elastography value to accurately diagnose the severity of liver fibrosis.
