A 6-yr-old boy underwent a total body Ga-67 citrate imaging study because of a large mass of Hodgkin's lymphoma in the left neck and the left anterior chest wall region. The images showed intense uptake in the left neck extending anteroinferiorly to the left upper chest wall corresponding to the left neck and chest region. In addition, there was mild cervical-upper thoracic scoliosis with conve...

OBJECTIVES To review the findings of the patients with Sjögren's syndrome (SS) having technetium99-m-pertechnetate (99mTc-pertechnetate) and gallium67- citrate (Ga-67) salivary gland scintigraphy in the past eight years. METHODS The patients with SS, who were referred to our department for salivary gland scintigraphy during January -2008December 2015 were studied using both 99mTc-pertechnetat...

This study evaluated the effective dose of Ga-67 for a patient undergoing Ga-67 citrate nuclear examination by applying thermoluminescent dosimeter (TLD) technique and an indigenous water phantom. The Ga-67 radionuclide remaining in the body inevitably generated a measurable internal dose even though gamma camera scanning took only minutes to complete the clinical examination. For effective sim...

Although non-Hodgkin's lymphoma of the gastrointestinal tract is common, primary esophageal lymphomas represent less than 1% of all gastrointestinal tumors. We report a case of primary non-Hodgkin's lymphoma of the esophagus. Ga-67 scintigraphy showed characteristic intense accumulation in the esophageal wall. The histopathology belonged to the category of mucosa-associated lymphoid tissue lymp...

It is aimed to evaluate Gallium-67 scintigraphy (GS) and CT for predicting clinical outcome in lymphoma patients who undergo autologous stem-cell transplantation (ASCT). Forty patients undergoing ASCT, had GS before and at 100 days post-transplantation (D-100). Patients were followed for 6-61 months and 15 had repeat GS at 200 days post-transplantation (D-200). All patients underwent computed t...

Fogh, J., Bertelsen, Sv., and Schmidt, A. (1974). Thorax, 29, 26-31. Diagnostic value of 67Ga-scintigraphy in chest surgery. Gallium-67 (67Ga) has a high affinity for malignant tissue. The diagnostic value of 67Ga-scintigraphy for differentiating between malignant and benign disease was studied in 109 patients with lesions of the chest discovered by radiological examination. Histological diagno...

The venom of the Eastern coral snake Micrurus fulvius can cause respiratory paralysis in the bitten patient, which is attributable to β-neurotoxins (β-NTx). The aim of this work was to study the biodistribution and lymphatic tracking by molecular imaging of the main β-NTx of M. fulvius venom. β-NTx was bioconjugated with the chelator diethylenetriaminepenta-acetic acid (DTPA) and radiolabeled w...

Straight GaN nanowires (NWs) with diameters of 50 nm, lengths up to 10 μm and a hexagonal wurtzite crystal structure have been grown at 900°C on 0.5 nm Au/Si(001) via the reaction of Ga with NH3 and N2:H2, where the H2 content was varied between 10 and 100%. The growth of high-quality GaN NWs depends critically on the thickness of Au and Ga vapor pressure while no deposition occurs on plain Si(...
