CT abdomen general
The general principles of the CT abdomen examination.
Pathology - Liver & Gallbladder
Liver
A normal liver enhances homogeneously (irrespective of the scan phase). The liver receives about 80% of its blood through the portal vein (= nutrient-rich blood from the intestines). The remaining 20% is supplied by the hepatic artery.
If focal liver pathology is present, it is important to document its location. This may be crucial to any surgical options. Using the Couinaud classification, the liver is subdivided into eight individually functioning segments. Each segment has its own afferent hepatic artery and portal vein, and efferent hepatic vein and efferent bile ducts (fig. 6).
