    Segment I
     

    Subxiphoid transverse view. Segment I is bordered posteriorly by the inferior vena cava, laterally by the ligamentum venosum and anteriorly by the left portal vein.

     
    Area of Interest: unknown; Imaging Technique: Segment I;

    Sagittal oblique view. Segment I is clearly seen anterior to the inferior vena cava.

    Left lobe

    Subxiphoid transverse view. The umbilical portion forms the crossbar of the H. Segment IV is the largest of the left lobar segments.

    Right lobe

    Sagittal midaxillary intercostal view. The right portal vein forms the crossbar of the H. The branches to segments V and VIII form the upper limb of the H. The branches to segments VI and VII form the lower limb of...

    Right lobe

    Transverse oblique subcostal view. The branch for segment VI is more oblique oriented downwards in the direction of the right kidney. The lateral border of this segment is the rib cage.

    Transverse oblique subcostal view. The three hepatic veins form a W with its base on the inferior vena cava. The hepatic veins separate the following segments: the left hepatic vein separates segment II from segment...

     
    Area of Interest: unknown; Imaging Technique: Hepatic veins;

    Transverse oblique subcostal view. Note that the right portal vein (cross-sectional view) separates the more superficial segment V from the deeply situated segment VIII.

Subxiphoid transverse view. Segment I is bordered posteriorly by the inferior vena cava, laterally by the ligamentum venosum and anteriorly by the left portal vein.
 
Sagittal oblique view. Segment I is clearly seen anterior to the inferior vena cava.
 
Subxiphoid oblique view. The left portal vein, with branches to segments II,III and IV, forms a sideways H. The branch leading to segment II is a linear continuation of the left portal vein, completing the lower horizontal limb of the H. Segments I and III are located to the left. Segment IV is located around the right anterior limb of the H.
 
Subxiphoid transverse view. The umbilical portion forms the crossbar of the H. Segment IV is the largest of the left lobar segments.
 
Sagittal midaxillary intercostal view. The right portal vein forms the crossbar of the H. The branches to segments V and VIII form the upper limb of the H. The branches to segments VI and VII form the lower limb of the H.
 
Transverse oblique subcostal view. The branch for segment VI is more oblique oriented downwards in the direction of the right kidney. The lateral border of this segment is the rib cage.
 
Transverse oblique subcostal view. Segment VII is also more oblique oriented. Note the right hepatic vein that separates segment VII from segment VIII (not shown in the image). The lateral border of this segment is the diaphragm.
 
Transverse oblique subcostal view. The three hepatic veins form a W with its base on the inferior vena cava. The hepatic veins separate the following segments: the left hepatic vein separates segment II from segment III (not shown in the image); the middle hepatic vein separates segment IV from segment V (not shown in the image) and segment VIII and the right hepatic vein separates segment V and VIII from segments VI and VII (not shown in the image).
 
Transverse oblique subcostal view. Note that the right portal vein (cross-sectional view) separates the more superficial segment V from the deeply situated segment VIII.
