conclusions: this study provides detailed information and case samples of radiodine contamination artifacts and non-physiological, non-metastatic extra-thyroidal i-131 accumulation in whole-body i-131 imaging. introduction: radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. differentiated thyroid cancers have the ability to trap iodine. therefore, rad...

PURPOSE The radioiodine ablation therapy is required for patients who underwent a total thyroidectomy. Through a comparative review of a low iodine diet (LID) and a restricted iodine diet (RID), the study aims to suggest guidelines that are suitable for the conditions of Korea. MATERIALS AND METHODS The study was conducted with 101 patients. With 24-hour urine samples from the patients after ...

Staging and risk stratification predicate the postoperative management of thyroid cancer patients, determining not only the need for (131)I therapy or alternative options (conservative management without ablation, surgical reintervention, or external-beam radiation therapy) but also the long-term follow-up strategy. This paper presents the progress made in the field of thyroid cancer imaging by...

In hyperthyroidism three major treatment modalities are currently available: antithyroid drugs, radioiodine and surgery, each of which presents advantages and restrictions (Surk et al.,1990). RAIT is considered as the most comfortable and economical approach of hyperthyroidism treatment caused by Graves ́ disease or toxic nodular goiter. Such treatment is indicated in patients with/or without fu...

Patients with advanced thyroid cancer may benefit from l-thyroxine treatment at doses that suppress serum TSH level, local treatment interventions, and radioiodine therapy. In those patients who are refractory to radioiodine therapy and in whom progressive disease has been documented, the efficacy of cytotoxic chemotherapy is poor. Encouraging results have been obtained with the use of kinase i...

BACKGROUND Differentiated thyroid cancers (DTC) often form metastases in neck lymph nodes, lungs and bones. Other metastases--to the brain, kidneys, skin and liver are rare. Liver metastases of DTC occur in the terminal phase of the disease and predominantly do not accumulate radioiodine. Functional (accumulating radioiodine) metastases are very rare. MATERIAL AND METHODS In an 85 year old pa...

INTRODUCTION Suspicion of a neoplasm is one of the contraindications to radioiodine therapy in benign thyroid disease. The aim of this study was to present an optimal qualification scheme for fine-needle aspiration biopsy (FNAB) to rule out neoplastic lesions prior to radioiodine therapy. MATERIAL AND METHODS 4207 patients with hyperthyroidism were referred for 131I therapy in 2000-2006. Prio...

Controversy remains regarding the optimal dose calculation with radioiodine therapy for patients with Graves' disease. Here, we focused our analysis on data concerning the patient's pretreatment background, an empirically set dose of radioiodine and the post-treatment thyroid function, and investigated those factors that affected the outcome. The subjects consisted of 38 patients diagnosed as h...
