1. Liver segmentation is based on the distribution characteristics of the portal system, divided into segments I to VIII.

2. Liver segmentation is distinguished according to the distribution characteristics of the portal system through the Couinaud segmentation method. During segmentation, the liver is divided clockwise into eight segments, namely segments I to VIII. Segment I is the caudate lobe, segment II is the superior segment of the left lateral lobe, segment III is the inferior segment of the left lateral lobe, segment IV is the left medial lobe, segment V is the inferior segment of the right anterior lobe, segment VI is the inferior segment of the right posterior lobe, segment VII is the superior segment of the right posterior lobe, and segment VIII is the superior segment of the right anterior lobe.

3. Liver segmentation is commonly used in CT imaging diagnosis and surgical procedures, playing a significant role in clinical practice. Each segment of the liver has inflow and outflow blood vessels as well as a biliary system, which can assist in diagnosis, determine the location of lesions, and provide guidance for treatment. It also allows for more accurate resection of liver segments during surgery.

4. After becoming ill, it is crucial to promptly cooperate with doctors for treatment. The earlier the treatment, the better the recovery effect, and it can also prevent the occurrence of other complications.
