| 摘要 |
The invention relates to a metal-radionuclide-labelled particulate composition which may be used in the form of a dry aerosol for lung scintigraphy, in particular, for the examination of the mucociliary transport, or for radiotherapy. The composition comprises radioactive labelled particles on a base of silica gel, another silicaceous material or a non-swelling polymer, at the surface of which organic ligands are bound covalently which comprise thiol-, amino-, alkylamino-, oxime-, dithiocarbamate-, xanthate-, thiosemicarbazone-, or dithiosemicarbazone groups or combinations thereof. The invention further relates to a method of preparing the composition and to a kit for carrying out the method. |
