Cirrhosis can be diagnosed with ultrasound, CT, and MRI, and these imaging modalities can also be used to evaluate for possible complications of cirrhosis, such as portal hypertension or hepatocellular carcinoma.
Liver ultrasound is a valuable diagnostic tool for assessing liver anatomy, size, and pathology. It is a non-invasive, painless, and relatively quick procedure that does not involve exposure to ionizing radiation.

Diffuse hepatic steatosis, also known as fatty liver, is a common imaging finding and can lead to difficulties assessing the liver appearances, especially when associated with focal fatty sparing.
Siderotic regenerative nodules are hyperdense to liver on precontrast imaging and become isodense to liver on post contrast phases. CT arterial portography. Contrast injection into the superior mesenteric artery (after arterial vascular access). Regenerative nodules are generally visualized as enhancing nodules surrounded by lower attenuation ...
Ultrasound. dilated portal vein (>13 mm): non-specific. biphasic or reverse flow in the portal vein (late stage): pathognomonic. enlarged paraumbilical veins 8: pathognomonic. portal-systemic collateral pathways (collateral vessels/varices) splenomegaly. ascites. cause of portal hypertension often identified, most commonly cirrhosis. CT and MRI
One should remember that a large number of patients will have concomitant cirrhosis, and thus also be at risk for bland portal vein thrombosis from synthetic dysfunction of clotting factors. Ultrasound. Variable appearance depending on the individual lesion, size, and echogenicity of background liver. Typically:
Ultrasound, CT, and MRI are helpful in detecting hepatic metastases and evaluation across multiple post-contrast CT series, or MRI pulse sequences are necessary.
The role of imaging is to demonstrate fat deposition in the liver, determine if cirrhotic changes are present, and to exclude other possible diagnoses. For general features of fatty deposition in the liver, see diffuse hepatic steatosis. Liver biopsy may be needed in indeterminate situations to establish the diagnosis. Ultrasound
This case demonstrates ultrasound features of liver cirrhosis complicated with gross ascites. No feature of portal hypertension was demonstrated.
