<p>The invention refers to a method of preparing an iron oxide composition and an iron oxide composition for therapeutic treatment of a living body. The method comprises the steps of providing fine grain iron oxide, introducing the fine grain iron oxide into a liquid carrier medium applicable for therapeutic purposes and dispersing the fine grain iron oxide in the liquid carrier medium, including the novel step of completing the fine grain iron oxide with at least one isotope of low activity for a period sufficient for introducing the fine grain iron oxide into an organ targeted of the living body or at least one isotope capable of being activated by neutrons and decaying after the period or transforming under influence of the neutrons to a high activity isotope of short life time before transforming into a stable isotope. The composition as proposed comprises a liquid carrier medium, the liquid carrier medium being applicable in a living body and fine grain iron oxide made of at least one iron oxide selected from the group consisted of ferrous oxide, ferric oxide and ferroferric oxide forming a dispersion in the liquid carrier medium, wherein the fine grain iron oxide constitutes a solid carrier medium for bearing at least one isotope of low activity for a period sufficient for introducing the fine grain iron oxide into an organ targeted of the living body or at least one isotope capable of being activated by neutrons and decaying after the period or transforming under influence of the neutrons to an isotope of short life time radiating with high activity before transforming into a stable isotope, the stable isotope being not toxic.</p> |
