The Liver Imaging Reporting and Data System (LI-RADS) standardizes the interpretation, reporting, and data collection for imaging examinations in patients at risk for hepatocellular carcinoma (HCC). It assigns category codes reflecting relative probability of HCC to imaging-detected liver observations based on major and ancillary imaging features. LI-RADS also includes imaging features suggesting malignancy other than HCC.
Grading and staging refers to a semiquantitative assessment of the necroinflammatory activity (grade) and degree of fibrosis (stage) in relation to chronic hepatitis.
Alcoholic liver disease (ALD) encompasses a spectrum of injury, ranging from simple steatosis to frank cirrhosis.
Indications for liver transplantation
1- Acute liver failure
- Acute hepatitis A
- Acute hepatitis B
- Drug/toxin hepatotoxicity
Arterial pH <7.3 (irrespective of the grade of encephalopathy)
Components of NAFLD Activity Score (NAS) and Fibrosis Staging
Modified Child-Pugh classification of severity of liver disease according to the degree of ascites, the plasma concentrations of bilirrubin and albumin, the prothrombin time, and the degree of encephalopathy.
