Wedge biopsy: a surgical biopsy in which a larger amount of tissue (typically up to 1 cm³) is obtained under direct surgical control.

Transvenous liver biopsy: a minimally invasive procedure performed under imaging guidance in which the liver is accesed via a catheter in the jugular vein and passed down into the hepatic veins. Performed in patients with a high bleeding risk or a large amount of intraabdominal fluid (ascites).
