Overview
An abdominal MRI may be helpful in the diagnosis of alcoholic liver disease. Findings on MRI can not confirm the cause of the liver disease but they are suggestive of underlying liver disease. An MRI can be expensive as an initial choice of diagnostic study and does not yield any advantages when compared to an ultrasound in the setting of alcoholic steatosis.
MRI
An abdominal MRI may be suggestive of underlying liver disease and findings on MRI include:[1][2][3]
- Cirrhosis:
- Enlarged caudate lobe
- Visualization of the right posterior hepatic notch
- Smaller size regenerative nodules

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]
