Thyrotoxicosis and radioiodine therapy: Does the dose matter?
1consultant, Diabetes Day care centre University Hospital of Ayr, Scotland, United Kingdom.
Abstract:
There are 3 treatment options for thyrotoxicosis: Antithyroid drugs, Surgery and radioiodine. The choice of treatment varies geographically. Radioiodine therapy is preferred in the United States. The aim of radioiodine is to destroy sufficient thyroid tissue to cure the hyperthyroidism. There is a lack of consensus towards what dose of radioiodine should be used. Several methods are used to determine the dose. In our practice we administer 400 MBq to patients with Graves and in patients with large multinodular goiter, we would administer 800 MBq.
