Quiz 3 Flashcards

Diagnosis based on this Positive Contrast Study of the Stomach
Gastric Ulceration
*You can see Filling Defects
If a _____ study is Necessary, Survey Radiographs of the Abdomen should always be obtained prior

Best Radiographic View to Diagnose Gastric Dilation Volvulus
Right Lateral
Four Differential Diagnoses for Microhepatia
Liver Shunting- Young Animal
Chronic Hepatitis- Older Animal
Cirrhosis- Older Animal
Diaphragmatic Hernia- Soft Tissue Opacity within the Thoracic Cavity and history of Trauma
What can be Diagnosed in this Portogram Radiograph?
Single, Extra Hepatic Portocaval Shunt
*Immediate Opacification of the Caudal Vena Cava- Not Normal. Should not see Opacification in the Heart Prior to Opacification of the Liver
