Imaging Tests
Magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound are all imaging techniques that are useful in detecting and defining the complications of cirrhosis, such as ascites and hepatocellular carcinoma. These imaging tests can also provide information on the extent of liver damage.

Liver Biopsy
A liver biopsy is the only definite method for confirming a diagnosis of cirrhosis. It also helps determine its cause, treatment possibilities, the extent of damage, and the long-term outlook. For example, patients with chronic hepatitis C who show no significant liver scarring when biopsied may have a low risk for cirrhosis.
A biopsy involves a doctor inserting a thin biopsy needle, guided by ultrasound, to remove a small sample of liver tissue. Local anesthetic is used to numb the area. Patients may feel pressure and some dull pain. The procedure takes about 20 minutes to perform.
The biopsy may be performed using various approaches, including:
- Percutaneous Liver Biopsy. This approach uses a needle inserted through the skin over the liver area to obtain a tissue sample from the liver. Various forms of needles are used, including those that use suction or those that cut out the tissue. This approach should not be used in patients with bleeding problems, and it must be used with caution in patients with ascites or severe obesity.
