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...

Suspicion for Cardiac Amyloidosis (CA) led a 75-year-old male patient with fatigue, dyspnea, and palpitations to be subjected scintigraphic myocardial investigation technetium-99m-pyrophosphate (99mTc-PYP, or PYP scan) in order distinguish transthyretin-related CA (ATTR) from the light-chain (AL) form. A characteristic anamnesis of bilateral carpal tunnel syndrome, vertebral canal stenosis, sen...

A 45-year old man who had refractory right chylothorax after esophagectomy for esophageal cancer underwent lymphoscintigraphy with Tc-99m human serum albumin. Focal abnormal uptake was seen in the mid abdomen on planar image 30 minutes after the tracer injection. SPECT/CT delineated the extent of the accumulation between the anastomotic site and the right pleural effusion area. SPECT/CT had a g...

The aim of this study was the investigation of absorbed dose to the kidneys, spleen, and liver during technetium-99 m ethylene dicysteine and technetium-99 m diethylenetriaminepentaacetic acid ((99m)Tc-EC and (99m)Tc-DTPA) kidney scan. Patients who had been prepared for the kidney scan, were divided into two groups (Groups 1 and 2). The first group (Group 1) and the second group (Group 2) recei...

Med., 2007, 211 (4), 379-385 ── Technetium-99m labeled human serum albumin (Tc-99m HSA) is an important radiopharmaceutical for clinical applications, such as cardiac function tests or protein-losing gastroenteropathy assessm...

parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. treatment is by surgical excision, but about 10% of the lesions may be in ectopic locations. pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, ct, or mr], may simplify surgery, and reduce patient morbidity. however, the reports of the accuracy of the currently a...

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...

A series of 253 consecutive patients with proved primary hyperparathyroidism due to parathyroid tumours was reviewed. There were 68 (26.9%) men and 185 (73.1%) women, with a median age of 57 years (range 13-82 years). All patients, prior to successful parathyroidectomy, underwent one or more preoperative localization procedures such as: neck ultrasonography (US) in 191 (75.5%), (201)Tl/(99m)Tc-...

OBJECTIVE To determine the results of scan-directed unilateral neck exploration for primary hyperparathyroidism. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. PATIENTS Patients who underwent parathyroid surgery for primary hyperparathyroidism between January 2000 and December 2007 were included. MAIN OUTCOME MEASURES The demographic, imaging, biochemical, and patholo...
