Why Is This Test Done?

Your doctor may recommend this test if they suspect liver problems such as liver cancer, cirrhosis, hepatitis, or fatty liver disease. It can also help check for liver damage after exposure to toxins or medications.

What Happens During the Procedure?

You’ll lie on your back on an exam table while a CT scanner takes detailed images of your liver. A needle guided by the CT images will collect a small tissue sample. You may feel pressure or a slight pinch, but you’ll be awake and alert during the procedure.

Preparation and Recovery

Before the procedure, you’ll likely be given a local anesthetic to numb the area. You may be asked to fast for a few hours beforehand. Afterward, you’ll need to rest for a short time and may experience mild bruising or soreness. Follow your doctor’s instructions for recovery.

Risks and Complications

While rare, risks include bleeding, infection, or puncturing other organs. Your doctor will explain the potential risks and how they’re minimized during the procedure.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
