Claims
- 1. In a process for radiologically examining a part of the body of an animal, the improvement comprising contacting said body part with an effective amount of a radiopaque agent comprising a non-toxic monobrominated acyclic perfluorocarbon.
- 2. The process of claim 1 wherein said radiopaque agent comprises a perfluoroalkyl bromide having 6 to 8 carbon atoms in the molecule.
- 3. The process of claim 1 wherein said radiopaque agent is CF.sub.3 (CF.sub.2).sub.6 CF.sub.2 Br.

- 7. The process of claim 1 wherein said body part is the gastrointestinal tract.
- 8. The process of claim 1 wherein said body part is the tracheobronchial tree and the lungs.
- 9. A non-toxic radiopaque emulsion consisting essentially of an aqueous phase, an effective amount of a monobrominated acyclic perfluorocarbon and a minor amount of an emulsifying agent.
- 10. The emulsion of claim 9 wherein said perfluorocarbon is a perfluoroalkyl bromide having 6-8 carbon atoms in the molecule.
- 11. The emulsion of claim 10 wherein said perfluorocarbon is CF.sub.3 (CF.sub.2).sub.6 CF.sub.2 Br.
