ABDOMINAL ORGANS

The liver, kidneys, and spleen are routinely evaluated by ultrasound. Cysts, tumors, kidney stones and gallbladder calculi are some of the findings which can be seen with ultrasound. The lower left image is a transverse US of the abdomen. The body of the pancreas is marked with the stars. In this patient, the pancreas is well visualized which is unusual because gas within the stomach, which lies anterior to the pancreas, often obscures it from being imaged.

It is easy to distinguish blood vessels from parenchyma.The image on the right is a transverse US of the superior portion of the liver. This shows the confluence of the right, middle, and left hepatic veins which are marked with stars.
