1.19.1\ Scanning Method

The patient should be on fast for 8–12h and in a supine position. Probe is placed in the right midclavicular line seventh or eighth intercostal spaces, scanning toward right posterior-superior.

1.19.3\ Measuring Method and Normal

Measuring inner diameter of the right portal vein and the right intrahepatic duct. Inner diameter of the right portal vein should be 0.6–1.2 cm. Inner diameter of the duct should be less than 0.3 cm.

1.19.2\ Section Structure

Longitudinal section of the right portal vein and its branches, oblique scan of the right anterior lobe and the right posterior lobe of the liver as well as the gallbladder. A cross section of the right hepatic vein. The intrahepatic duct accompanying the right portal vein can be shown clearly if its branches are dilated.

1.19.4\ The Clinical Application Value

The right portal vein, right intrahepatic duct and its branches, as well as their location relationship can be shown in this plane. We can also observe the size, shape, and parenchyma echogenicity of the right liver.
