Clinical utility of pneumogastrography in dogs.

Pneumogastrography utilizes negative contrast media such as air or carbonated beverages to improve visualization of luminal contents and mucosal surfaces within the stomach. Pneumogastrography as a diagnostic technique in cases of gastric disease has not been widely described in the veterinary literature and is a procedure that may yield additional information not obtained from survey radiographs. This technique is useful in the diagnosis of luminal and mucosal gastric diseases. In this article, the pneumogastrography technique and relevant literature are reviewed. Six case examples are included that demonstrate the utility of pneumogastrography in dogs with gastric disease.
