1.6.1\ Scanning Method

The patient should be on fast for 8–12 h with a supine position. Probe is placed on the subxiphoid transversely.

1.6.2\ Section Structure

Oblique section of the left external hepatic lobe, caudate lobe, umbilical, inferior vena cava and sagittal section of the left portal vein.

1.6.3\ The Clinical Application Value

To observe the size, shape, and parenchyma echogenicity of the left external lobe of the liver, especially to observe the area near the external edge of the left external hepatic lobe to distinguish the mass in the liver from that outside.

1.7.1\ Scanning Method

The patient should be on fast for 8–12 h with a supine position. The subxiphoid transverse scanning is made, and the direction of the acoustic beam is toward the posterior-superior.

1.7.2\ Section Structure

Transverse-oblique section of the left hepatic lobe and caudate lobe. Sagittal segment and transverse segment of the left portal vein, inferior vena cava, and abdominal aorta. The caudate lobe

anterior to the inferior vena cava is separated from the left lobe by the fissure for the ligamentum venosum.

1.7.3\ The Clinical Application Value

To observe the size, shape, and parenchyma echogenicity of the left lobe and caudate lobe of the liver. To determine whether there is diffused or space-occupying lesions in those area. The caudate lobe may be enlarged in some patients with hepatic cirrhosis.
