Abstract
Radiolabeled colloid compositions, a process for their preparation, and their use in the treatment of rheumatoid arthritis are disclosed. A radionuclide of Sm-135, Ho-166, In-155m, Y-90, Gd-159, La140, Lu 177 or Yb-175 is sorbed to a previously prepared iron-hydroxide colloid. The radiolabeled colloid compositions are comprised of spherical aggregations containing greater than 50 % of the radioactive metal in iron-hydroxide particles.
