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...

BACKGROUND Measurement of radioactive iodine uptake (RAIU) is an important aspect of the assessment and treatment of patients with hyperthyroidism. Its uncertainty affects how much of a true change in RAIU can be detected as well as appropriateness of the therapy dosage upon which it is based. In this study, a method of estimating the reproducibility and least significant change (LSC) values fo...

Over 500 cases of thyroid cancer were diagnosed in Belarus between 1986 and 1995 among persons exposed as children (under 15 years of age) to radioactive contamination from the Chernobyl nuclear accident. There is little doubt that radioactive iodine isotopes emitted during the nuclear explosion and subsequent fire were instrumental in causing malignancy in this particular organ. Comparison of ...

The concentration of iodine species can be measured using several different analysis methods. One of the most wellknown methods involves iodine titration with a thiosulfate solution. Total iodine can be analyzed using spectrometry, such as inductively coupled plasma-atomic emission spectrometry (ICP-AES), atomic absorption spectrometry (AAS) and inductively coupled plasma-mass spectrometry (ICP...

Primary hyperparathyroidism is a very rare complication following radioactive iodine therapy. There is typically a latency period of more than a decade following radiation exposure and, therefore, it is observed almost exclusively in adults. Consequently, pediatricians are not aware of the association. We present a case of primary hyperparathyroidism due to a solitary parathyroid adenoma occurr...

Radioactive isotopes of iodine are themost common radiological toxins from nuclear accidents due to their high release and high enrichment in human thyroid. Among the radioactive isotopes, long-lived I can not only be used for the estimation of the radioactive risk of short-lived radioactive isotopes of iodine to humans and ecosystems, but also for the investigation of the biogeochemical cycle ...

Backgroud: Several treatment options are available for patients with hyperthyroidism, such as antithyroid drugs and radioactive iodine. Recently, increasing number of patients with hyperthyroidism take lithium carbonate in combination with radioactive iodine. Numerous clinical studies have been done to evaluate the efficacy and safety of lithium carbonate in combination with radioactive iodine ...

OBJECTIVE Using nuclear medicine imaging, we explored suitable acquisition window parameters for assessing the distribution of iodine-125 radioactive seed implantation. SUBJECTS AND METHODS We studied 30 patients with various tumors (21 of which were liver cancers) who had received iodine-125 radioactive seed implantation and had undergone whole-body scintigraphy. Scintigraphy images were acq...

introduction:  the use of radioactive iodine (131i) has become an important adjunct to the treatment of thyroid cancer and hyperthyroidism. salivary gland has the ability to concentrate radioactive iodine under normal circumstances. salivary gland dysfunction and dry mouth are the common side effectsof high-dose radioiodine therapy. the purposeof this study was to determine the absorbed dose of...
