Use of MRI in the diagnosis as well as a complex with the target portion and the Tc complex

摘要

Aza present invention, - improved ^{99m Tc} radioactive metal complex composition of diaminedioximes ligands, radiopharmaceutical formulation containing the same, about the kit for the preparation of radiopharmaceuticals. Aza - diaminedioximes - By technetium metal complexation studies of the target molecule chelate complexes, technetium species rise to multiple was found. The present invention, improved aza was suppressed the presence of technetium species undesirable - to provide diaminedioximes complex technetium metal complex composition.
