|Title:||Gentisic acid salts as radiographic scanning agent stabilizers|
|Abstract:||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.99m TcO.sub.4.sup.-) 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.|
