1.3.1\ Scanning Method

The patient should be on a supine position. Probe is placed in the right subcostal sagittally, about 1 cm from the right midclavicular line, perpendicular to the horizontal line. That the patient keeps breathing can make the liver move down so that a clear section of the right kidney can be obtained.

1.3.2\ Section Structure

Longitudinal section of the right kidney and the hepatic lobe. The right liver and right kidney fossae between the right posterior lobe of the liver and upper pole of the right kidney.

1.3.3\ Measuring Method and Normal

The largest anteroposterior diameter of the right hepatic lobe measured from the top of the anterior capsule to the posterior capsule. Anteroposterior diameter should be less than 14 cm in the normal liver.

1.3.4\ The Clinical Application Value

(1) This is a standard section for measuring anteroposterior diameter of the right liver lobe. To observe the size, shape, and parenchyma echogenicity of the right liver. (2) The liver and kidney fossae are located at the lowest area of the abdominal cavity. If effusion appears, it would be shown here the earliest in supine position. (3) Generally, the right liver visceral surface closes to the upper pole of the right kidney. Retroperitoneal space-occupying lesions can

increase the distance between the right liver and the kidney. (4) This section can be used to make a differential diagnosis among the liver, right kidney, and right retroperitoneal lesions. When the patient takes a deep breath, the lesion in the liver or in the kidney could move with the breath, but the lesions located at the retroperitoneum would not move.

1.3.5\ Notices

We think that the largest anteroposterior diameter measuring of the liver is very important in estimating the size of the right liver lobe because it can give the real right liver size with a minimum error and can make up for the deficiency of the largest oblique diameter measurement. The normal of anteroposterior diameter of the right liver is about 12–14 cm, >14 cm for a an anomaliy.
