Abstract
Liver biopsies are among the most common procedures performed by the interventional
radiologist. Liver biopsies may be performed through the percutaneous or transjugular
approaches. Ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI)
may be used for imaging guidance. Transjugular liver biopsies are generally reserved
for specific circumstances in which the percutaneous method is associated with increased
risk to the patient, such as coagulopathy, or when portal pressure measurements are
desired. In addition, endobiliary biopsy through percutaneous transhepatic tracts
may be an important means of assessing biliary strictures when the endoscopic route
is impossible. This article serves as a general review of the multiple diagnostic
hepatic interventions that may be performed by the interventional radiologist.
