RADIOACTIVE DIAGNOSTIC AGENT AND NON-RADIOACTIVE CARRIER THEREFOR

摘要

The invention relates to a radioactive diagnostic agent which comprises deferoxamine, a physiologically active compound chemically connected thereto either directly or via any chemical bonding moiety, and a radioactive metallic element forming a chelating compound with the bonded deferoxamine. Such agents have a high stability even after being administered into a human body and show substantially the same behavior in the human body as the physiologically active compound itself.
