Overview
Abdominal CT scan may be helpful in the diagnosis of alcoholic liver disease. Findings on CT scan suggestive of hepatic steatosis and cirrhosis may be seen.
CT scan
- Findings on CT scan suggestive of alcoholic liver disease include:
- Non-contrast CT scan for detecting hepatic steatosis:[1][2]
- Macroscopic fat in the liver
- Liver to spleen attenuation ratio greater than ten hounsfield units indicates hepatic steatosis
- Cirrhosis:[3]
- Atrophy of the right lobe of the liver
- Hypertrophy of the caudate lobe of the liver
- Hypertrophy of the lateral segment of the left lobe
- Parenchymal nodularity
- Attenuation of hepatic vasculature
- Splenomegaly
- Venous collaterals
- Ascites
- Non-contrast CT scan for detecting hepatic steatosis:[1][2]
- CT of a cirrhotic patient shows a liver with a shrunken, nodular appearance.
