although the basic question of ablative threshold dose for ablation of thyroid remnant after surgery yet remains unanswered. but radioiodine therapy is being used as a standard method of treatment. in present research, treatment responces for 100 patients with thyroid cancer treated with 3660 mbq of ¹³¹i were studied. significant response differences between female group (66%) and male group (3...

introduction:differentiated thyroid carcinoma (dtc) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (tg), diagnostic iodine-131 whole body scan (dxwbs) and sonography. some patients with undetectable tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. methods: in this study, we e...

In this clinical study, we have compared routine diagnostic dose (131)I scan and (99m)TcO4(-) thyroid scintigraphy with therapeutic dose (131)I imaging for accurate thyroid remnant estimation after total thyroidectomy. We conducted a retrospective review of the patients undergoing total thyroidectomy for differentiated thyroid carcinoma (DTC) and subsequently receiving radioactive iodine (RAI) ...

Objective: The current study aimed to determine the efficacy of radioiodine-131 (131I) ablation therapy with thyroid hormone replacement one day before 131I administration in patients with well-differentiated thyroid cancer (DTC). Methods: This retrospective study included 29 patients who underwent 131I therapies twice for DTC during 6-12 months.  Since all the patients obviously had residual l...

Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. We investigated clinical outcomes of remnant thyroid ablation with a low radioiodine activity in Korean patients with low to intermediate-risk thyroid cancer. For remnant thyroid ablation, 176 patients received radioiodine of 1.1 GBq, under a s...

BACKGROUND Complete excision is important for proper surgical treatment of thyroid disorders. Functional thyroid tissue can be identified based on the level of serum thyroglobulin (Tg), which is produced only by the thyroid follicular cells, and nuclear scan. METHODS Serum thyroid stimulating hormone (TSH), free thyroxin (FT4), basal (unstimulated) Tg and anti-Tg antibody (anti-Tg ab) were me...

Parotid metastasis originated from papillary thyroid carcinoma is extremely rare, especially as the first presentation of the disease. We present a 70-year-old man with a history of painless swelling in the right side of the neck. He was evaluated for parotid tumor and histopathologic examination revealed a poorly differentiated carcinoma in the parotid gland with suspicion of thyroid origin. T...

The rationale and objectives for radioactive iodine (RAI) ablation remain perplexing to many. This review addresses the meaning, clinical context and the goals of "ablation": the RAI treatment after a total thyroidectomy. This article also aims to clarify the definition of a total thyroidectomy and how a thyroid remnant can introduce a confounding factor in the postoperative management of patie...
