Abstract
The liver is located in the epigastrium and right hypochondrium and is bordered superiorly by the diaphragm. It is divided into eight functional segments according to blood supply; this facilitates tumor localization and surgical planning. Modalities used to image the liver are ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), nuclear imaging, and invasive angiography. Generally, MRI and CT are the modalities of choice for imaging liver cirrhosis and its complications. The characterization and staging of liver malignancies such as hepatocellular carcinoma (HCC), cholangiocarcinoma, and liver metastases are also preferably done by MRI and CT; Ultrasound and nuclear imaging are less specific, while invasive angiography is reserved mainly for therapeutic procedures for HCC.
