Summary for Patent: 4,432,963
Title: Radiographic scanning agent
Abstract:A composition and method for the preparation of a technetium-99m-based scanning agent are disclosed. The scanning agent is prepared from .sup.99m Tc, in a +3, +4 and/or +5 oxidation state, and a methanehydroxydiphosphonate bone-seeking agent which carries the radionuclide to bone mineral.
