KEY FACTS

  • Preprocedure

    • Procedure

      • Post Procedure

        TERMINOLOGY

        • Definitions

          • Radioactive iodine (I-131; sodium iodide) therapy for hyperthyroidism
            • Take up by thyroid follicular cells via iodide transporter, similar to nutritional iodine
            • 0.606 MeV beta emissions destroy thyroid tissue over 1.5-5.0 months
