Choice of contrast medium in sialography
Oral Surgery, Oral Medicine, and Oral Pathology
|March 1, 1984
Summary
Several radiopaque contrast media were evaluated for sialography, with Conray 80, Amipaque 440, Lipiodol UF, Myodil, and Duroliopaque showing promise. Further clinical studies are recommended to confirm their suitability for sialography.
Area of Science:
- Radiology
- Medical Imaging
- Salivary Gland Imaging
Background:
- Contrast media for sialography were initially developed for other medical uses.
- Investigating their properties for sialography is crucial for optimizing diagnostic procedures.
Purpose of the Study:
- To evaluate the suitability of eleven radiopaque substances for sialography.
- To assess contrast qualities, evacuation rates, and potential tissue toxicity.
Main Methods:
- In vitro studies to determine contrast and evacuation properties.
- Animal experiments to assess effects on salivary and extraglandular tissues.
Main Results:
- Five agents (Conray 80, Amipaque 440, Lipiodol UF, Myodil, Duroliopaque) showed suitability.
- Effectiveness is contingent on avoiding glandular overfilling.
Conclusions:
- Selected contrast media show potential for sialography.
- Further prolonged clinical investigation is advised for definitive agent selection.
