introduction: this study was launched to evaluate the sensitivity and specificity of 99mtc-ciprofloxacin to distinguish infection foci induced by staphylococcus aureus and inflammation lesions induced by carrageenan in the rat foot in comparison with 67ga-citrate scintigraphy. methods: the labeling and quality control of 99mtc-ciprofloxacin kits have been performed according to the manufacture...

OBJECTIVE To develop a study aiming at optimizing myocardial perfusion imaging. MATERIALS AND METHODS Imaging of an anthropomorphic thorax phantom with a GE SPECT Ventri gamma camera, with varied activities and acquisition times, in order to evaluate the influence of these parameters on the quality of the reconstructed medical images. The (99m)Tc-sestamibi radiotracer was utilized, and then t...

BACKGROUND Omitting extensive lymph node dissection could reduce esophagectomy morbidity in patients without lymph node metastases. Sentinel node biopsy may identify abdominal or thoracic lymph node metastases, thereby differentiating treatment. Feasibility of this approach was investigated in Western European esophageal cancer patients with advanced disease, without lymph node metastases at di...

The concentration of radioiodinated (Fab')2 fragments of cardiac specific antimyosin antibody in myocardial infarcts has been shown previously to be inversely proportional to regional myocardial blood flow. The myocardial localization of antibody fragments has also been visualized by gamma camera scintigraphy. We now correlate the site of 121I-antimyosin (Fab')2 uptake with histochemical and hi...

Primary hyperparathyroidism due to parathyroid adenomas may be associated with ectopic parathyroid gland localization in 20-25% of the patients. We report herein the excision of an ectopic parathyroid adenoma which was detected in the thymus gland by gamma probe intraoperatively. A 38-year-old patient presented to our clinic with a history of bilateral nephrolithiasis, chronic hypercalcaemia, a...

Myocardial MIBG scintigraphy is established in the diagnosis and differential diagnosis of Parkinson's disease (PD). Numerous studies address the pathophysiological impact of myocardial MIBG scintigraphy: the myocardial MIBG uptake correlates with the clinical phenotype of PD; the background of this phenomenon is unclear. Furthermore MIBG scintigraphy enables to study the extracranial Lewy body...
