Abstract
Stable compositions, useful as technetium-99m-based imaging agents, comprise reductic acid or certain structurally-related compounds in combination with a pertechnetate reductant or dissolved in pertechnetate-99m solution. The compositions are especially useful, in combination with a phosphate or phosphonate bone-targeting carrier, for skeletal imaging.
