Overview
There have been recent advances towards newer imaging modalities to help detect and quantify hepatic fibrosis and cirrhosis. These investigations are comparable to the gold standard that is liver biopsy to confirm the diagnosis of liver cirrhosis.
Other Imaging Findings
- More recent imaging techniques include:[1][2]
- Transient elastography (FibroScan)
- Acoustic radiation force impulse
- Magnetic resonance elastography
- The listed newer imaging techniques have the following characteristics:
- Note: Alcoholic steatohepatitis often coexists with fibrosis, since these tests are based on measurement of liver stiffness, it is better to wait until AST is less than 100U/L during alcohol withdrawal in order to preserve the diagnostic accuracy of this test.[3]
