a 63-year-old woman presented with a history of hyperthyroidism symptoms over two years, referred for thyroid scintigraphy. in the hospital archives we have met her previous thyroid scintigraphy showing a hot nodule in the upper part of right thyroid lobe. however, her recent thyroid scintigraphy was showing only cold nodules but no hot nodule, giving an impression that she had some treatment t...

Introduction: In spite of large number of studies regarding relation between thyroid cancer and childhood irradiation, contraversy still exists management of these patients. This study tries to find optimal method of thyroid evaluation in this group. Methods and patients: In a recall program using mass media in Khorasan, all patients with childhood irradiation were invited for thyroid eva...

Background: Local ablative treatments play an important role for patients who cannot be treated surgically. Radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. Microwave ablation (MWA) is a new minimally invasive treatment promising several improvements. The aim of this retrospective study was to evaluate the eff...

Introduction: Extraosseous accumulation of 99mTc – methylene diphosphonate (MDP) may be due to neoplastic, dystrophic, hormonal, inflammatory, ischemic, traumatic or excretory disorders. 99mTc-MDP incidental thyroid uptake is not frequent and is possibly caused by the presence of dystrophic or metastatic calcification, biopsy procedure and presence of beni...

OBJECTIVES We aimed to investigate the reliability of thyroid ultrasonography (US) and scintigraphy in determining the type of thyroid dysgenesis (TD). METHODS The study included 82 children (8.0±5.6 years) with a diagnosis of TD by thyroid scintigraphy with (99m)Tc and/or US. The patients were re-evaluated 6.0±5.1 years after the diagnosis. Thyroid US was performed in all cases, regardless o...

PURPOSE To compare MR with thallium-201 scintigraphy in the follow-up of patients who have undergone thyroidectomy and modified radical neck dissection for differentiated thyroid cancer. METHODS Both MR imaging and 201Tl scintigraphy were performed in 39 patients after surgery for differentiated thyroid cancer. Ten patients did not have recurrence; 29 patients had 51 recurrent tumors in the n...

A strong association between malignant lymphoma and Hashimoto's thyroiditis has frequently been reported. However, it is difficult to detect the lymphomatous transformation of Hashimoto's thyroiditis in the early stage. The purpose of the present study was to examine the usefulness of 67Ga scintigraphy in the diagnosis and evaluation of the therapeutic effects during follow-up, in patients with...

introduction: various radiopharmaceuticals, including 67ga, 201tl, and 99mtc-sestamibi have been used to differentiate benign from malignant thyroid nodules. 99mtc-tetrofosmin, a lipophilic cationic radiotracer, and 99mtc-sestamibi have also been reported to accumulate in thyroid tumors. in this study, we evaluated the role of 99mtc-tetrofosmin in the differentiation of malignant from benign th...
