Overview
CT
- CT scan is usually performed among patients with Alcoholic Hepatitis to exclude other abnormalities including neoplasm, biliary obstruction or infiltrative liver disease.
- CT scan can predict severity and outcome of Alcoholic Hepatitis by presence of the following findings:
- Splenomegaly, defined as spleen dimension ≥ 13 cm
- Ascites
- Varices; defined as moderate if esophageal varices < 3 mm or paraesophageal varices < 5 mm, severe varices defined as esophageal varices > 3 mm or paraesophageal varices > 5 mm
- Liver length to mid clavicular line
- Liver attenuation, measured approximately 5 cm2 regions of interest in the right, central, and left liver at the level of the portal vein
- Spleen attenuation, measured approximately 5 cm2 regions of interest in the center of spleen
- Liver heterogenecity, mild heterogenecity considered as if 1 to 50% of hepatic parenchyma was heterogenous, more than 50% of heterogenous area considered moderate to severeheterogenecity
hepatic parenchyma was heterogenous
