  • Title: Technetium-99m complexes of dimethylaminomethylene diphosphonate (DMAD)--II. Biological distributions of 99mTc-DMAD components isolated by anion exchange HPLC.

    Journal: Int J Rad Appl Instrum B; 1989; 16(3):313-7. PubMed ID: 2497091.
    Abstract:
    HPLC isolated components of 99mTc(NaBH4)-DMAD mixtures exhibit significantly different biological properties than do analogous components of 99mTc(NaBH4)-MDP and 99mTc(NaBH4)-HEDP mixtures. Most importantly, 99mTc-DMAD components desorb from normal bone whereas analogous 99mTc-MDP and 99mTc-HEDP components do not. However, within an osteogenic rat model, an HPLC isolated 99mTc-DMAD component does not exhibit an unusually high abnormal/normal tibia uptake ratio.
