A 64-year-old man presented with clinical unilateral thyroiditis after chronic left neck trauma from his car seat belt. Thyroid function tests were normal. The initial thyroid Tc-99m pertechnetate scan demonstrated decreased uptake in the entire left lobe of the thyroid. The follow-up scan 1 month later showed a more normal uptake in the left lobe. This patient's clinical course, laboratory val...

A 58-old-man underwent (18)F-fluorocholine PET/CT for restaging of prostate cancer because of a rising level of prostate-specific antigen.( 18)F-fluorocholine showed no significant tracer uptake at the site of the prostatectomy or the pelvic lymph nodes. Incidental high tracer uptake was observed in a 26 × 23 mm left thyroid nodule. A benign tumor of the thyroid (oncocytic adenoma of thyroid) w...

objective: diabetes mellitus and thyroid disease are the two common endocrinopathies seen in adult population. studies to evaluate thyroid disorders in patients with type 2 diabetes are lacking. the aim of this study was to compare prevalence of thyroid dysfunction and autoim-munity in type 2 diabetic patients with age and sex matched non-diabetic control group. material and methods: among pati...

Whole-body I-131 scintigraphy (I-131 WBS) has been a helpful diagnostic procedure for evaluating the existence of residual thyroid bed remnants as well as possible metastasis in patients with differentiated thyroid cancer after surgery [1, 2]. In the interpretation of I-131 WBS, breast uptake may be misread as thyroid cancer lung metastasis if it occurs with an atypical pattern or is clinically...

radioactive iodine therapy is commonly used as an adjuvant therapy in follicular and papillary thyroid carcinoma and also in the treatment of graves’ disease. the basis of which is the accumulation of radioactive iodine by the sodium-iodide symporter (nis) in the thyroid gland. expression of nis by extrathyroidal tissues including islets of pancreas has been reported. radioactive iodine uptake ...

OBJECTIVE Since Graves' disease (GD) is resistant to antithyroid drugs (ATDs), an accurate quantitative thyroid function measurement is required for the prediction of early responses to ATD. Quantitative parameters derived from the novel technology, single-photon emission computed tomography/computed tomography (SPECT/CT), were investigated for the prediction of achievement of euthyroidism afte...

Background. False-positive pulmonary radioactive iodine uptake in the followup of differentiated thyroid carcinoma has been reported in patients with certain respiratory conditions. Patient Findings. We describe a case of well-differentiated papillary thyroid carcinoma treated by total thyroidectomy and radioiodine ablation therapy. Postablation radioiodine whole body scan and subsequent diagno...

The sodium-iodide symporter (NIS) mediates iodide uptake into the thyrocytes, which is important for the diagnosis and therapy of thyroid disorders. Decreased ability to uptake iodide in thyroid carcinomas reduces the efficacy of radioiodine therapy, and retinoic acid (RA) treatment reinduces iodide uptake. The effectiveness of treatment depends not only on iodide uptake but also on the ability...

INTRODUCTION In the last decade, (18)F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET and PET/CT) has become one of the major diagnostic tools used in oncology. A significant number of patients who undergo this procedure, due to non-thyroidal reasons, present incidental uptake of (18F-FDG) in the thyroid. The aim of the study was to compare the SUVmax (standardized uptake value)...
