Stomach

Normal stomach

 

The stomach often demonstrates low-level activity similar to that in the liver and is usually identified by its position and configuration. Activity is usually within the walls of the stomach and is usually fairly uniform. Hiatal hernias are often associated with inflammation and resultant increased activity that can usually be differentiated from a mass in the lower thorax by inspection of the CT images. Often a small focus of activity can be seen at the gastroesophageal junction. This activity may be related to normal physiological activity of the lower esophageal sphincter or may be related to reflux and some degree of associated inflammation.
