Pancreas Anatomy

The left adrenal gland is frequently crescent-shaped.

Adrenal Glands Ultrasound

The left adrenal gland often extends relatively far downward toward the renal hilum.

The adrenal gland is seen to consist of three layers: two echodense outer layers and a hypoechoic middle layer.

"esophagus

The gastroesophageal junction is identified between the liver, aorta, and diaphragmatic crura.

Liver Ultrasound Anatomy

The cardia displays a typical pointed, triangular shape in transverse section.

The cardia adjoins the body of the stomach, which presents a seemingly chaotic pattern of solid, liquid, and gaseous contents.

Esophageal Junction Ultrasound Anatomy

Below the cardia, the body of the stomach lies against the aorta.

Longitudinal Image Liver

The esophagus and the cardia are located between the liver and aorta in the upper abdominal longitudinal scan.

Ultrasound Gastoespogeal Junction

The first step in identifying the cardia and body of the stomach is to demonstrate the gastroesophageal junction.

The Antrum And Body The Stomach

Without special patient preparation, the body of the stomach produces a heterogeneous echo pattern posterior to the left lobe of the liver.

Liver Ultrasound Anatomy

The body of the stomach is consistently located behind the left lobe of the liver. It may be fluid-filled and clearly defined, or empty and difficult to identify.

Longitudinal Ultrasound Images Liver

A longitudinal scan through the upper midabdomen demonstrates the characteristic triad of stomach, liver, and pancreas.

The antrum extends to the right, coming between the pancreas and liver. It is difficult to visualize at that location.

The second part of the duodenum lies between the liver, gallbladder, vena cava, and head of pancreas.

Vena Cava Pancreas Anatomy

The antrum often extends quite far downward, especially when the stomach is full and the subject is standing upright.

With a high-resolution device and favorable scanning conditions, five layers can be distinguished in the gastric wall.

A scan through the antrum is best for differentiating the layers of the gastric wall.
