Evaluation of the efficacy of potassium iodide preparation for radioactive iodine therapy in Graves' disease - Evaluation of the efficacy of potassium iodide preparation for radioactive iodine therapy in Graves' disease

RAIU before RAIT (p=0.0018), dose of 131-I (p=0.0037), FT4 at RAIT (p=0.0034), and thyroid gland weight one year after RAIT (p=0.0065) showed significant differences. Thyroid gland weight, dose of 131-I based on thyroid gland weight, difference in FT4 between before drug discontinuation and at RAIT, and thyroid function at one year after RAIT did not show any significant differences. These results suggest that most patients without large goiter and/or highly aggressive disease may be safely and efficiently treated with RAIT and KI pretreatment until 4 days before therapy.
