tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and anemia. tc-...

thyroid scintigraphy has been helpful in detecting and evaluation of thyroid nodules. sodium pertechnetate tc-99m is the most commonly used radionuclide for thyroid imaging because of its general availability, favorable dosimetric characteristics and low cost. but, there are reports of occasional disparity in isotope uptake in lesions compared with radioiodide. in order to determine percentage ...

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.

Gastrointestinal duplication cysts are a rare congenital malformation in the gastrointestinal tract, most commonly seen ilium. The present study reported child with mid ileal cyst ofthe ectopic gastric mucosa that was diagnosed by Technetium-99m pertechnetate single-photon emission computed tomography-computed tomography (SPECT-CT) scintigraphy. can massive lower bleeding early childhood (Mecke...

Accumulation of both Tc-99m pertechnetate and radioiodine upon scintigraphy in thyroid carcinoma and/or in its metastases is a rare occurrence. In this paper we describe a patient who was taken to surgery for left lobectomy of the thyroid with follicular adenocarcinoma and who had accumulation of both I-131 and Tc-99m pertechnetate in lung metastases. The accumulation of I-131 was less than tha...

OBJECTIVES This study is to assess the prognostic value of (99m)Tc-pertechnetate thyroid scintigraphy for predicting the outcomes of fixed low dose of radioiodine therapy (RIT) in a cohort of Chinese Graves' disease (GD) patients. MATERIALS AND METHODS This is a retrospective study of GD patients who received RIT with a single dose of radioiodine (5 mCi). All the patients received (99m)Tc-per...

We report the case of a 71-year-old woman who was referred to our institute with a solid nodule in the right thyroid lobe and hypercalcemia. Ultrasound revealed a well-vascularized right thyroid nodule that was identified as a cold area by (99m)Tc-sodium pertechnetate scan. Fine-needle aspiration showed a follicular lesion and blood tests revealed hypercalcemia and hyperparathyroidism. A (99m)T...
