1.2.1\ Scanning Method

The patient should be on fast for 8–12 hours with a supine position. Probe is placed vertically in the subxiphoid, slightly inclined to the right.

1.2.2\ Section Structure

Longitudinal section of the quadrate lobe, caudate lobe, and inferior vena cava (posterior liver segment) and oblique scan of the portal vein, middle hepatic vein, and common bile duct are shown.

1.2.3\ Measuring Method and Normal

Measuring the diameter of the inferior vena cava (segment of the posterior liver and segment of entering the right atrium).

1.2.4\ Clinical Application Value

The placeholder lesions, expansion, narrowness, blood clots, etc, in the inferior vena cava such as Budd-Chiari’s syndrome are diagnosed by this plane.
