A technique for barium esophagram in the opossum.
Single and double contrast barium esophagram examinations were performed on 42 opossums. Each animal was anesthetized with pentabarbital sodium, a catheter was placed in the esophagus, and barium or barium and air were injected into the esophagus. Two radiographs per second for 7 seconds were taken. The radiographs were reproducible and of high quality.
