The liver is a pyramid-shaped organ that lies within the upper right side of the abdomen. In a typical liver biopsy, a needle is inserted through the rib cage or abdominal wall. The needle goes into the liver to take a sample for examination.
The procedure can also be performed by inserting a needle into the jugular vein. A catheter is then passed through the veins, down to the liver, to take the sample.
