A liver biopsy is a procedure where a small sample of liver tissue is removed from the liver, using a special biopsy needle. This sample is then sent to the laboratory for analysis.
The biopsy needle is guided into the liver by an interventional radiologist, using an ultrasound machine to make sure the needle is inserted into an ideal position. When in position, the biopsy needle makes a loud click, and takes a sample.
