2.1.1\ Scanning Method

Patient should be on fast for 8–12 h with a left lateral decubitus position. Probe is put on the right ninth, tenth, or eleventh intercostal space at the axillary front or between the axillary front and middle axillary. The right liver can serve as an acoustic window to visualize the echogenic adrenal gland.

2.1.2\ Section Structure

The right adrenal gland is triangular or pyramidal and caps the upper pole of the right kidney. The oblique section of the kidney, spleen, and pancreatic tail and the longitudinal section of the splenic vein are shown.

2.1.3\ Measuring Method and Normal

The length and thickness of the right adrenal gland are measured. Thick diameter measurement should be vertical to length diameter measurement.

2.1.4\ Clinical Application Value

If the patient is obese or has much bowel gas, it may be difficult to recognize the triangular adrenal gland. If the adrenal gland appears round, it may be abnormal.

2.2.1\ Scanning Method

Patient should be on fast for 8–12 h and take a right lateral decubitus position. Probe is put at the left ninth, tenth, or eleventh intercostal spaces or left subcostal. After showing the coronal section of the left kidney, the transducer should move to the left superior to the left upper pole of the left kidney to show the left adrenal gland. The spleen or water-filled stomach can serve as an acoustic window to obtain the best visualization of the left adrenal gland.

2.2.2\ Section Structure

The longitudinal section of the left adrenal gland, spleen and the oblique section of the left kidney are shown. The left adrenal gland is semilunar, and located at anterior-superior to the upper pole of the left kidney. The oblique section of the abdominal aorta is on the right.

2.2.3\ Measuring Method and Normal

The largest thick and length diameter of the left adrenal gland is measured. The thickness measurement should be vertical to length diameter . The normal length diameter is 2.29 ± 0.11 cm. The thick diameter is 0.61 ± 0.15 cm.

2.2.4\ Clinical Application Value

This plane can be used to diagnosis enlargement or space-occupying lesions of the left adrenal gland as well as the lesions around it.

2.2.5\ Notice

If the patient is obese or has much bowel gas, it may be difficult to recognize the adrenal gland. Technical proficiency is also influential to visible rate.
