1. A combined formulation comprising:
- i) a first administrable composition comprising a first pre-targeting vector; and
ii) a second administrable composition comprising a targetable diagnostic and/or therapeutically active agent, said agent comprising a suspension in an aqueous carrier liquid of a reporter comprising gas-containing or gas-generating material, said reporter further comprising a moiety having affinity for said pre-targeting vector and a second vector, the first and second vectors binding to different targets on the same or different cells.

i) administering to said body a pre-targeting vector having affinity for a selected target; and
thereafterii) administering said agent comprising a vector having affinity for said pre-targeting vector.
-
-
27. A method as claimed in claim 26 wherein said pre-targeting vector comprises a monoclonal antibody.
-
28. A method as claimed in claim 24 which comprises the steps:
-
i) administering to said body a combined formulation; and
thereafterii) administering a substance capable of displacing or releasing said agent from its target.
-
-
29. A method as claimed in claim 24 wherein said agent further comprises a therapeutic compound.
-
30. A method as claimed in claim 29 wherein said therapeutic compound is covalently coupled or linked to the reporter through disulphide groups, and a composition comprising a reducing agent capable of reductively cleaving said disulphide groups is subsequently administered.
