In patients affected by differentiated thyroid cancer, the whole-body scan (WBS) with 131-radioiodine, especially when performed after a therapeutic activity of 131I, represents a sensitive procedure for detecting thyroid remnant and/or metastatic disease. Nevertheless, a wide spectrum of potentially pitfalls has been reported. Herein we describe a 63-year-old woman affected by follicular thyro...
Since all isotopes of any element have identical chemical behaviour, the radioactive isotopes of iodine are metabolised in the same way as normal iodine, and become highly concentrated in normal or over-active thyroid tissue and, in some circumstances , in thyroid cancer tissue. It may consequently be possible to destroy part or all of such tissues by the effects of the intense local beta radia...
UNLABELLED Graves's disease is the most common cause of hyperthyroidism. There are three current therapeutic options: anti-thyroid medication, surgery, and radioactive iodine (I 131). There are few data in the literature regarding the effects of radioiodine therapy on the larynx and voice. The aim and the AIM os this study was: to assess the effect of radioiodine therapy on the voice of Based...
Differentiated thyroid cancers are typically iodine-avid and can be effectively treated with radioiodine. In most patients, radioiodine treatment is done for ablation of residual tissue, and in these cases the focus should be on using the minimum effective dose. Adjuvant therapy can be done to reduce the risk of recurrence, but optimal patient selection and dose are unclear. Patients with advan...
A radioiodine whole body scan relies on the fact that differentiated thyroid cancer is more efficient at trapping circulating radioiodine than any other tissues.(Hyer, Newbold et al. 2010) Therefore, when I-131 is administered it accumulates in the thyroid cancer tissues and a radioiodine whole body scan plays an important role in the management of patients with differentiated thyroid cancer. U...
background: radioiodine therapy has proven to be an effective method in the treatment of patients with differentiated thyroid carcinoma after thyroidectomy. the scope of this study is to describe a method to obtain the dose of organs using medical internal radiation dosimetry (mird) method. at the end, the results of mird calculations were compared with thermoluminescent dosimeter (tld-100). ma...
INTRODUCTION Graves disease (GD) is the most common cause of hiperthyroidism, and the most common treatment options are surgery, antithyroid drugs and radioiodine therapy. In radiodosimetric calculations to determine radioiodine dosage it is possible to use thyroid volume estimatives based on ultrasound or scintigraphy. OBJECTIVE The present study aimed to correlate these methodologies emphas...
S NMMI has been increasing dialogue and collaboration with other societies with similar interests over the last several years. One important area is in diagnosis and management of differentiated thyroid cancer (DTC)— radioiodine theranostics. With the efforts of multiple individuals and committees, we have significantly increased our dialogue with SNMMI members as well as collaboration with oth...
UNLABELLED This aim of this retrospective study was to determine the impact of glucocorticoid therapy on the effective (131)I half-life in radioiodine therapy for Graves disease. METHODS Three hundred fifteen consecutive Graves disease patients undergoing radioiodine therapy at our institution between August 2004 and January 2009 were enrolled. We investigated the influences of thyroid state ...
Background: Due to its use of ionising radiation, the field of nuclear medicine is a unique and significant part of medical diagnostics and patient treatment. The aim of this study was to assess the internal exposure of nuclear medicine employees to radioiodine 131I and technetium 99mTc as well as to assess the external exposure doses. Material and Methods: The radioiodine 131I and technetiu...
