Fawzi, M B

Stable compositions, useful as technetium-99m-based scintigraphic agents, comprise gentisic acid or a pharmaceutically-acceptable salt or ester thereof in combination with a pertechnetate reducing agent or dissolved in pertechnetate-99m(/sup 99/ /sup m/ TcO/sub 4/-) solution. The compositions are especially useful in combination with a phosphate or phosphonate material which carries the radionuclide to bone, thus providing a skeletal imaging agent.
