Significant differences in findings were seen between the intake amounts of iodine-131 that were derived from direct measurements and the estimated intake from environmental monitoring data at the Fukushima accident. To clarify these discrepancies, we have investigated the iodine-131 and tellurium-132 body burdens of five human subjects, who after being exposed to a radioactive plume, underwent...

The large numbers of studies on the postoperative management of differentiated thyroid carcinoma allows us to use adjuvant treatment and follow-up studies more selectively based on patient risk for recurrence and mortality. Recurrent differentiated thyroid carcinoma is more easily and more effectively treated with early diagnosis. With this in mind, patients who are at high risk for life-threat...

Abstract Purpose Radioactive iodine (RAI) whole-body scan is a sensitive imaging modality routinely used in patients with differentiated thyroid cancer to detect persistent and recurrent disease. However, there can be false-positive RAI uptake that lead misdiagnosis misclassification of patient’s stage. Recognizing the causes false positivity avoid unnecessary testing treatment as well emotiona...

clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...

Objective: To assess the value of the diagnostic whole body I scan after thyroidectomy and I ablation. Design: Retrospective analysis of all patients with differentiated thyroid cancer treated in one centre between 1990 and 2000. Results: A total of 153 consecutive patients who underwent diagnostic scanning following ablative therapy were identified. This diagnostic scan was positive in 20 pati...

Objective(s): It is difficult to investigate the whole-body distribution of an orally administered drug by means of positron emission tomography (PET), owing to the short physical half-life of radionuclides, especially when 11C-labeled compounds are tested. Therefore, we aimed to examine the whole-body distribution of donepezil (DNP) as an acetylcholinesterase inhibitor by means of 11C-DNP PET ...
