Radioactive Iodine Uptake
Also written as RAIU.
| Radioactive iodine uptake (RAIU) scan | Etiology (diffuse vs nodular) | Uniform high uptake → Graves’; patchy → toxic multinodular; low uptake → thyroiditis |
What our notes say
- | Radioactive iodine uptake (RAIU) scan | Etiology (diffuse vs nodular) | Uniform high uptake → Graves’; patchy → toxic multinodular; low uptake → thyroiditis | (Hyperthyroidism and hypothyroidism)
- TSH receptor antibodies (TRAb) or Thyroid stimulating immunoglobulins (TSI) (Accept: Thyroid peroxidase antibodies, radioactive iodine uptake scan) (Chemical Pathology Practice Examination)
- The treatment of patients exposed to 131I involves using potassium iodide to block radioactive iodine uptake, monitoring thyroid function, administering thyroid hormone replacement if hypothyroidism develops, and monitoring for radiation-induced thyroid cancer. (Thyroid Hormone)
