Abstract: The invention is directed to a method for preparing a microsphere comprising a lanthanide metal phosphate complex, a microsphere, a powder comprising a number of the microspheres, a suspension comprising the microsphere or the powder, the use of the microsphere, a method for detecting a tumor, and a therapeutic composition comprising the microsphere, the powder, or the suspension. The invention provides a method for preparing a microsphere that comprises a lanthanide metal phosphate complex, the method comprising: (a) providing an organic lanthanide metal complex microsphere, wherein the lanthanide metal is present in an amount of more than 20 wt.

Abstract: The invention provides a scanning suspension comprising a particle which is capable of at least in part disturbing a magnetic field, wherein said particle comprises a diameter of at least 1 ?m, and use thereof for obtaining a scanning image. Preferably, said particle comprises holmium and a composition capable of essentially maintaining its structure during irradiation. A particle of the invention is suitable for preparing a kit of parts, comprising a diagnostic and a therapeutic composition which both comprise particles of the invention with essentially the same chemical structure, wherein said therapeutic composition is more radioactive than said diagnostic composition. Said kit of parts is especially suitable for treatment of a tumor. First, the distribution of a particle of the invention within an individual can be determined with a scanning image obtained with said scanning composition.

Abstract: An irradiation vessel is made from such material and in such form that it can also be used as administration vessel of a medicine contained therein, this medicine first being irradiated with neutrons in a nuclear reactor and subsequently being administered as radioactive medicine to a patient without the medicine having to be moved outside the vessel intermediately. To prevent additional handling operations, with the risk of contamination of the medicine, higher radiation doses to personnel and radioactive contamination of the environment when vessels are used in which the irradiation and administration take place separately, a vessel has been developed which allows a medicine to be irradiated and to be directly administered to the patient thereafter via an external carrier liquid.
