    • The present invention provides methods and compositions for improved medical diagnostic imaging and therapy for the treatment of rheumatoid arthritis. The compositions are derived from apatite particles including, but not limited to, hydroxyapatite, fluoroapatite, iodoapatite, carbonate-apatite, and mixtures and derivatives thereof. The compositions of the present invention contain a paramagnetic species incorporated into the apatite particles to improve magnetic resonance contrast and a radionuclide capable of providing a therapeutic dose of radioactivity. Also disclosed is a combination diagnostic/therapeutic composition and methods of performing medical diagnostic and therapeutic procedures which involve administering to a warm-blooded animal an amount of the above-described apatite particles containing a diagnostically effective amount of the paramagnetic ion and a therapeutically effective amount of the radionuclide and then performing the medical treatment and diagnostic procedures.

    • The present invention relates to novel radiopharmaceutical imaging agents having non-stannous reductants. Metallic compounds, such as Cu(I), Cu(II), Co(II), Fe(II), Sn(O), Zr(O), Cr(II) and Zn(O), will act to effectively reduce radionuclide containing solutions. Several non-metallic compounds, such as acids in general, dithionite, formamidine, formamadine sulfinic acid, phosphite, hypophosphite, dithiotreitol, hydrochloric acid, and borohydric acid may also be used to reduce radionuclide containing solutions. Moreover, it has been discovered that several agents, such as phosphines, sulfhydryl compounds, phosphites, thiols, thioethers, borates, borocyano groups, ascorbates and gentisates efficiently reduce radionuclide containing solutions and complex with the radionuclide at the same time. The present invention also relates to kits for forming radiopharmaceutical imaging agents, such kits including non-stannous reducing agents.
    • 本发明涉及具有非亚锡还原剂的新型放射性药物显像剂。 金属化合物如Cu(I),Cu(II),Co(II),Fe(II),Sn(O),Zr(O),Cr(II)和Zn(O) 含有放射性核素的溶液。 几种非金属化合物,例如一般的酸,连二亚硫酸盐,甲脒,甲酰胺亚磺酸,亚磷酸盐,次磷酸盐,二硫代醇,盐酸和硼酸也可用于还原含放射性核素的溶液。 此外,已经发现,多种试剂如膦,巯基化合物,亚磷酸酯,硫醇,硫醚,硼酸盐,硼氰基,抗坏血酸盐和龙胆酸盐同时有效地降低含放射性核素的溶液并与放射性核素复合。 本发明还涉及用于形成放射性药物成像剂的试剂盒,所述试剂盒包括非亚锡还原剂。
