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 dibrominated aliphatic perfluorocarbon or a brominated cyclic perfluorocarbon.
- 2. The process of claim 1 wherein said perfluorocarbon is selected from the class consisting of dibrominated acyclic perfluorocarbons, monobrominated cyclic perfluorocarbons, and dibrominated cyclic perfluorocarbons.
- 3. The process of claim 2 wherein said perfluorocarbon has 2 to 12 carbon atoms in its molecule.
- 4. The process of claim 3 wherein said perfluorocarbon has 6 to 8 carbon atoms in its molecule.
- 5. The process of claim 3 wherein said perfluorocarbon has the formula BrCF.sub.2 -CF.sub.2 Br.
- 6. The process of claim 3 wherein said perfluorocarbon has the formula Br-(CF.sub.2).sub.4 -Br.
- 7. The process of claim 3 wherein said perfluorocarbon has the formula ##STR3##
- 8. The process of claim 3 wherein said perfluorocarbon has the formula ##STR4##
- 9. The process of claim 3 wherein said perfluorocarbon has the formula ##STR5##
- 10. The process of claim 1 wherein said perfluorocarbon is administered in the form of an aqueous emulsion.
- 11. The process of claim 1 wherein said perfluorocarbon is administered in the form of an aerosol.
- 12. A non-toxic radiopaque emulsion consisting essentially of an aqueous phase, an effective amount of a dibrominated acyclic perfluorocarbon, a monobrominated cyclic perfluorocarbon, or a dibrominated cyclic perfluorocarbon, and a minor amount of an emulsifying agent.
- 13. An emulsion in accordance with claim 12 which contains about 1 to 12 parts by volume of said perfluorocarbon for each part by volume of aqueous phase.
