Transjugular Liver Biopsy is a method of diagnosing cancer in the liver by using a long, thin biopsy device that is threaded into the jugular vein and guided into the liver. 

There are many ways to locate a lump in the liver (X-rays, computed tomography (CT) scans, magnetic resonance (MR) etc.). However, a diagnosis of cancer can only be confirmed by a pathologist examining a piece of the suspected tissue.  Using this technique, an interventional radiologist can obtain a samply of abnormal tissue from the liver without a patient having to undergo open surgery.
