Abstract: Applicants' invention relates to a method for dissolving a solute material in a container by contacting the solute with a solvent in another container. Applicants' method relies upon the difference in the specific gravities of the solvent and the solute to create a convection current between their respective containers. The material, either the solute or the solvent, having the larger specific gravity is placed above the material having the smaller specific gravity, and the two materials are brought into contact. The solute dissolves in the solvent, and the resulting solution, which has a lower or higher specific gravity than the solvent, causes a convection current which draws the heavier material down and the lighter material up. As the convection current proceeds, the undissolved solute continues to come into contact with fresh solvent accelerating the dissolution process.

Abstract: A cationic .sup.99m Tc.sup.III myocardial imaging agent is disclosed which has a relatively negative redox potential. This prevents in vivo reduction of the Tc(III) to Tc(II). The redox potential of the Tc(III) is controlled by complexing the Tc with both hard and soft atoms. Preferably four of the atoms complexed to the Tc(III) are hard atoms such as nitrogen or oxygen and the remaining two are soft atoms such as phosphorous or arsenic. These imaging agents are particularly useful in imaging the human heart.
