Abstract
Radionuclide complexes of phosphonate derivatives of bis(aminoalkyl)piperazine have been found which are useful for imaging and/or treating therapeutically the skeletal system to detect and treat bone tumors. These complexes clear readily through the kidneys and the ratio of uptake in bone to that in surrounding soft tissue is high.
