NCIt definition : A radioactive salt that is used as a reagent in the preparation of indium 111-labeled
radiopharmaceuticals. Indium 111-labeled radioconjugates are used as radioactive tracers
in nuclear medicine that detect malignant lesions and inflammatory tissues probably
due to an increased capillary permeability. Indium-111 chloride is particularly used
in the radiolabeling of the monoclonal antibodies satumomab pendetide, 7E11-C5.3 (CYT-356),
and ibritumomab tiuxetan. (NCI05);
