A technique for barium esophagram in the opossum
Laboratory Animal Science
|August 1, 1979
Summary
Barium esophagrams in opossums yielded high-quality, reproducible images. This study demonstrates the efficacy of barium contrast radiography for esophageal examination in this animal model.
Area of Science:
- Veterinary Radiology
- Comparative Anatomy
Background:
- Esophageal imaging is crucial for diagnosing conditions in veterinary medicine.
- Opossums are increasingly used as animal models in biomedical research.
Purpose of the Study:
- To evaluate the feasibility and quality of barium esophagrams in opossums.
- To establish a reproducible radiographic technique for opossum esophageal examination.
Main Methods:
- 42 opossums underwent single and double contrast barium esophagrams.
- Anesthesia and esophageal catheterization were performed prior to barium/air injection.
- High-frequency radiography (2 frames/second for 7 seconds) was utilized.
Main Results:
- Radiographs obtained were consistently reproducible.
- The quality of the barium esophagram images was deemed high.
Conclusions:
- Barium esophagrams are a viable and effective imaging modality for opossum esophagus.
- This technique provides high-quality, reproducible results for research and diagnostic purposes in opossums.
