NEUTRON ACTIVATED 153SM LABELLED MICROSPHERES

摘要

The present invention relates to a method of preparation of 153Sm labelled microspheres, comprising the steps of incorporating a 152Sm compound into insoluble ion-exchange resin or glass beads and subsequently performing neutron activation of the incorporated samarium microspheres. It further includes radioactive microspheres containing153SmCI3 or a hydrate thereof and the clinical use of such radiolabeled microspheres.
