Liver Radiology Key
In a portal venous phase CT, the right, middle, and left hepatic veins are usually filled with contrast-mixed blood and can be seen emptying into the inferior vena cava, which is found along the back side of the liver. The portal and hepatic veins divide the liver into segmental anatomy that allows radiologists and surgeons to be very specific.

PURPOSE: To evaluate qualitatively and quantitatively the current procedures for radiologic delineation of the segmental and subsegmental anatomy of the liver. MATERIALS AND METHODS: Vascular casts of 10 livers were examined with helical computed tomography (CT). Liver segmental and subsegmental anatomy were determined on the CT scans according to customary radiologic practice guidelines. CT.
segmental anatomy of the liver
The hepatic segmentation (lobes, parts, divisions and segments) is the oganization of the liver into parts, divisions and segments.
Liver Anatomy Segments
Liver segmentation for volumetric assessment is indicated prior to major hepatectomy, portal vein embolisation, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and transplant. Segmentation software can be categorised according to amount of user input involved: manual, semi-automated and fully automated.

They are classically described ('classic lobules') as hexagonal structures made of six vertically aligned portal canals with a central vein. However, microscopic evaluation of the liver usually shows a lack of classic liver lobule as a well-defined connective tissue septum is usually lacking. Liver lobules are enveloped by Glisson's capsule.

Segmental anatomy Traditionally, the liver was divided into four anatomical lobes: the right, left, caudate and quadrate lobes.

Couinaud classification of hepatic segments Radiology Reference
A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, arranged in a clockwise manner starting from the caudate lobe.

The middle hepatic vein separates the right liver from the left liver and the right hepatic vein separates the right posterior sector and anterior sector. The plane of the portal vein is used to divide the different segments into upper and lower sectors (this plane is correct for the segments of the right liver but false for segments II and III.

It is the preferred anatomy classification system as it divides the liver into eight independent functional units (termed segments) rather than relying on the traditional morphological description based on the external appearance of the liver. Terminology
Couinaud classification of hepatic segments Radiology Reference
sectorial branches will separate each sector of the right liver into two segments (5/8 and 6/7, respectively). In practice, it is convened that all these separations (sectorial and segmental) in the right liver occur at the level of the portal bifurcation. In the left liver, the left portal branch describes an arch towards the round ligament.

Future liver volume prior to major hepatectomy. Liver volumetry is indicated in patients undergoing major hepatic resection [], defined as resection of four or more segments according to the Couinaud classification [].Most hepatectomies are performed for the treatment of neoplasms, including primary liver cancer (e.g. hepatocellular carcinoma and cholangiocarcinoma), liver metastases (e.g.
Diagram and Wiring Diagram Of Liver Segments
The left hepatic artery runs vertically towards the umbilical fissure and supplies segments 1, 2 and 3. It usually gives off a middle hepatic artery branch that runs towards the right side of the umbilical fissure and supplies segments 4a and 4b 2 . Within the liver, the left hepatic artery divides into: medial segmental branch.
Couinaud classification of hepatic segments Radiology Reference
These vessels and segments include the celiac artery, the common and proper hepatic arteries, the left and right hepatic arteries and branches, the caudate lobe, and the portal vein and branches.
