Background. Topical diagnosis of primary hyperparathyroidism (PHPT) remains an urgent problem due to the high incidence persistence and recurrence after surgical treatment. At preoperative stage, a search for parathyroid hormone hyperproduction source is performed using instrumental methods: ultrasound, scintigraphy glands (PTG) multislice computed tomography (MSCT). The cause PHPT parathyroide...

Purpose: To demonstrate a rare clinical case of early recurrence verified primary genital lymphoma and the possibility 99mTc-1-Thio-D-glucose (99mTc-TG) SPECT/CT using to brain metastasis diagnosis. Material methods: A patient with diagnosis diffuse large B-cell underwent magnetic resonance imaging (MRI) assess extent disease. Post-treatment follow-up included 18F-FDG PET/CT. diagnose metastasi...

UNLABELLED Apoptosis, or programmed cell death (PCD), contributes to the decline in ventricular function in heart failure. Because apoptosis comprises a programmed cascade of events, it is potentially reversible, and timely intervention should delay the development of cardiomyopathy. (99m)Tc-Labeled annexin A5 has successfully been used for the noninvasive detection of PCD in myocardial infarct...

Lung fluid balance is critically dependent on capillary endothelial and alveolar epithelial barrier properties, and cytoskeletal components have been implicated in these barrier functions. In an earlier study, we perfused Clostridium botulinum C2 toxin, which effects selective loss of non-muscle F-actin, through isolated rabbit lungs: a severalfold increase in the capillary filtration coefficie...

BACKGROUND Bone infection is a common issue in infectiology. The gold standard for evaluating bone infection is the white blood cell (WBC) scan. In our practice the WBC scan is coupled with a bone scan. Discordances in the results of these two examinations are a common occurrence in daily practice. We decided to investigate the meaning of these discordances. MATERIALS AND METHODS Two hundred ...

In the past six years, 37 patients with gastrointestinal bleeding of obscure origin had their bleeding sites localised preoperatively or intraoperatively. Preoperative investigations followed a regime consisting of endoscopy, barium meal and follow through, small bowel enema, 99mTc pertechnetate scan, 99mTc-labelled red blood cell scan and selective coeliac and mesenteric angiography. Bleeding ...

Transmission-emission scanning of the thorax with a flood source of technetium-99m (99mTc), autologous 99mTc labelled red blood cells, and diethylenetriaminepenta-acetic acid (99mTc DTPA) allows measurement of thoracic tissue thickness and blood and interstitial volume per pixel of the gamma camera image. Volume of blood or interstitium per pixel divided by pixel area gives the thoracic tissue ...

Ambient particles are believed to be a specific health hazard, although the underlying mechanisms are not fully understood. There are data in the literature indicating fast and substantial systemic uptake of particles from the lung. The present authors have developed an improved method to produce ultrafine particles with more stable radiolabelling and defined particle size range. Fifteen subjec...

Colistin aerosols are frequently administered to patients with cystic fibrosis. However, questions arise concerning the effect of both jet and ultrasonic nebulizers on the properties of the drug. The aim of this study was to characterize the anti-Pseudomonas aeruginosa (PA) activity of colistin after jet (Pari LL) and ultrasonic (DP100) nebulization. A bench study was performed by capturing the...

BACKGROUND AND PURPOSE The brain distribution of 9mTc-hexamethylpropyleneamine oxime (HMPAO) correlates with regional brain perfusion, whereas 99mTc-ethyl cysteinate dimer (ECD) reflects not only perfusion but also the metabolic status of brain tissue. We compared 99mTc-ECD single-photon emission CT (SPECT) with 99mTc-HMPAO SPECT early after recanalization by local intraarterial thrombolysis (L...
