Overview
Overview
24-hour iodine-123 uptake scanning may be helpful in the diagnosis of autoimmune thyroiditis associated with autoimmune polyendocrine syndrome (APS). Autoimmune thyroiditis can be seen in any sub-type of APS but is more commonly seen in type 3 and type 2. Patients of APS with autoimmune thyroiditis present with decreased uptake of iodine-123, which can help in differentiating hypothyroidism seen in autoimmune thyroiditis from other causes.
