Figure 21.7 Normal gastrointestinal series using barium contrast media. (a) Survey right lateral projection. (b) Survey ventrodorsal
projection. (c) Lateral projection following oral administration of barium sulfate. Barium is seen in the stomach and small intestine.
The appearance of a “string of pearls” (arrow) in the small intestine is normal and is caused by normal intestinal contractions. (d)
Ventrodorsal projection showing barium sulfate in the stomach and small intestine (arrow). (e) Lateral projection showing that barium
contrast has reached the colon. An arrow indicates the cecum. Some contrast outlines the rugal folds of the stomach (arrowhead).
(f) Ventrodorsal projection. (g) Lateral projection following oral administration of barium sulfate in another cat. The colon should be
smoothly marginated. The cecum (arrow) is small. (h) Ventrodorsal projection showing that the descending colon may be on either the
right or left side of the abdomen. C, colon; S, spleen; St, stomach.
