The present invention provides novel radiopharmaceuticals useful for imaging the heart, brain, lungs, liver or kidneys, kits useful for preparing the radiopharmaceuticals, and methods of imaging the heart, brain, lungs, liver or kidneys in a patient in need of such imaging. The radiopharmaceuticals are comprised of technetium or rhenium radionuclide complexes of a ternary ligand system: one hydrazido or diazenido ligand, one aminoalcohol ligand, and one pi-acid ligand selected from phosphines, arsines, and imine nitrogen-containing heterocyles. The radiopharmaceuticals have the formula ML<1>L<2>L<3>, wherein the variables are as defined herein.
