Introduction: Nowadays, radioisotopes have a lot of therapeutic and diagnostic applications in nuclear medicine. The technetium-99m radioisotope is widely used in the diagnostic field. The technetium-99m radioisotope is widely used in the diagnostic field. In this study, in order to increase the absorption dose in thyroid cancer cells, the radioactive drug technetium-99m which ...

introduction: the aim of this study was to investigate the effect of methimazole on technetium-99m reabsorbing by thyroid gland , it may be possible to perform thyroid scan when the patients are on the methimazole, this can be time saving and decrease the adverse effects of discontinuing methimazole. patients and methods: among all the patients with hyperthyroidism who referred to nuclear medic...

HYPOTHESIS Preoperative parathyroid and thyroid imaging using technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (Tc 99m MIBI SPECT) and technetium Tc 99m sodium pertechnetate, respectively, in patients with parathyroid adenomas and concomitant multinodular goiters enables the selection of those suitable for minimally invasive radio-guided surgery. DESIGN One ...

introduction: the radioimmunoscintigraphy (ris) has found widespread clinical applications in  tumor  diagnosis.  human  epithelial  mucin,  muc1,  is  commonly  over  expressed  in  adenocarcinoma including 80% of breast cancers and represents a useful target for ris. the pr81  is  a  new  murine  anti-muc1  monoclonal  antibody  that  was  found  to  react  with  the  membrane  extracts of se...

The authors present a case of subhyoid ectopic thyroid with mediolateral location diagnosed by technetium-99m pertechnetate scan. The ectopia was associated with hypothyroidism and developmental retardation.

Key words: hyperparathyroidism-radionuclide-imaging; primary and secondary hyperparathyroidism [1–3]. With hyperplastic parathyroid glands tetrofosmin hyperplasia; Technetium-99m-diagnostic use; tetrofosmin imaging gives an overall sensitivity of 84% and a specificity of 75%, higher than those of Tc-99m sestam-ibi, ultrasonography and magnetic resonance imaging Renal history [1–2]. The former h...

AIM Various studies have been conducted for determining the most optimal method for the early diagnosis of local recurrent or distant metastatic thyroid cancers. The aim of this study was to evaluate the clinical utility of technetium-99m (Tc-99m)-labeled octreotide derivatives in the detection of recurrence or distant metastases in medullary thyroid cancer patients and to compare the lesions w...

Aim: This study aimed to determine the normal range for thyroid uptake of technetium-99m (99mTc) pertechnetate in a Turkish population.Methods: The retrospective included 73 (54 females, 19 males) consecutive euthyroid patients, all whom underwent scintigraphy using 99mTc-pertechnetate as component parathyroid adenoma localization. value at 20th minute was calculated each patient.Results: mean ...

BACKGROUND Thyroid imaging with isotopic iodide (123I) or technetium Tc 99m pertechnetate has been available for decades but is not routinely used in newborn infants diagnosed with congenital hypothyroidism (CH). Among clinicians who believe that presence, absence, or abnormal location of a thyroid does not alter management of CH, imaging is not advocated for anatomic diagnosis of CH. OBJECTI...
