We prospectively performed gamma correction pinhole bone scan (GCPBS) and histopathologic verification study to make simultaneous morphobiochemical diagnosis of trabecular microfractures (TMF) occurred in the femoral head as a part of femoral neck fracture.Materials consisted of surgical specimens of the femoral head in 6 consecutive patients. The specimens were imaged using Tc-99m hydroxymethy...

PURPOSE To report a case of dermatomyositis (DM) with secondary Sjögren's syndrome (SS) and propose the clinical application of technetium-99m pyrophosphate ((99m)Tc-PYP) scan. CASE REPORT A 50-year-old woman had progressive proximal muscle weakness of bilateral thighs, myalgia, tea-colored urine, and exercise intolerance for 6 months. Physical examination showed malar rash, V-sign, periungua...

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...

Isotope uptake during static radionuclide scanning and contrast enhancement during CT scanning, which may result from similar pathophysiologic mechanisms after ischemic infarction, were investigated in an animal model. Infarction was produced by transorbital occlusion of the middle cerebral artery in cats killed one, 2, 4, 8, or 16 days later. Sodium pertechnetate containing technetium-99m and ...

BACKGROUND AND PURPOSE Currently, most studies combine the small bowel transit examination with gastric emptying time examination. There are significant drawbacks to this method. The radiotracer does not enter the small intestine in a bolus and the starting time for transit in the duodenum is difficult to define. This makes the result unreliable. In this study, we used a commercial enteric caps...

The authors present a comparison of the findings for thallium-201 (Tl-201), Tc-99m MAG3 and Tc-99m MDP in subacute and chronic radiation nephritis in a 9-yr-old boy who was treated by radiation therapy for alveolar rhabdomyosarcoma of the left chest wall by a radiation port that partially included the left kidney. Tl-201 imaging three and six months later showed a cortical defect in the left ki...

bone involvement. Destruction is mediated through normal osteoclasts, which respond to local osteoclast-activating microenvironment [7]. Technetium-99m 2methoxyisobutylisonitrile (TC-99m MIBI) is a lipophilic agent that accumulates within living malignant cells due to the higher transmembrane electrical potential as a consequence of the higher metabolic rate than in the surrounding normal cells...

Meckel diverticulum is the most prevalent congenital abnormality of the gastrointestinal tract in children. The aim of this study was to review and analyze clinical data on the diagnosis and management of Meckel diverticulum in pediatric patients. The records of 102 pediatric patients (<14 years old) who underwent surgery for Meckel diverticulum at our institute between 2001 and 2015 were revie...

OBJECTIVE To perform a retrospective review of all patients receiving technetium-99m ((99m)Tc)-labelled sulesomab over a 4-year period to determine if soft tissue infections can be accurately identified. METHODS AND MATERIALS We reviewed the results of 124 (99m)Tc-sulesomab studies performed over a 4-year period. Of these, 34 were performed for undiagnosed fever in which soft tissue infection...
