摘要： Certain particle-emitting radionuclides, e.g. Samarium-153, have been complexed with certain alkylenepolyaminocarboxylic acid chelants. Compositions containing these complexes have been found useful in the treatment of calcific tumors in animals. The stability constant, log K, of the useful complexes is from about 14 to about 17 and the molar ratio of chelant to radionuclide in the compositions is such that the chelant is present in an amount sufficient to inhibit uptake of the radionuclide by soft tissue.
