Standard oesophageal scintigraphic techniques using 99mTc-colloids rarely identify oesophageal mucosal damage. Sucralfate can be labelled with 99mTc for the detection of oesophageal mucosal ulceration. This method uses two separate supine swallows of 10 MBq 99mTc-colloid in 10 ml, followed by a single supine swallow of 30 MBq 99mTc-sucralfate. The data are processed to give time-activity curves...

  Introduction: Many radiotracers have been used for sentinel node mapping with acceptable results. The main difference between these radiotracers is the particle size. In the current study, we reported defective labeling of Tc-99m antimony sulfide colloid which resulted in large particle size. Methods: Tc-99m-Antimony sulfide colloid was used for axillary sentinel n...

METHODS Thirty-two patients with clinical node-negative breast cancer underwent sentinel node localization study as part of a National Cancer Institute-sponsored multicenter trial. Anatomical and histopathologic characteristics of sentinel lymph node (SLN) and a kinetic analysis of nodal uptake were studied. Patients were injected with 1 mCi/4 ml unfiltered 99mTc-sulfur colloid in four divided ...

Filling defects are often observed on 99mTc sulfur colloid liver scans. Hot spots are much less frequently seen. Superior vena cava syndrome is the most frequent cause of this finding. In this report 3 patients with S.V.C and budd - Chiari syndrome with HOT SPOT on liver scan are presented. Mechanisms of scintigraphic patterns are reviewed.

introduction: there is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (i and ii) breast cancer patients. usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. in this study we evaluated this issue in our patients. methods: 40 patients with the clinical dia...

Contamination of the environment with antimony compounds may affect human health through the persistent exposure to small doses over a long period. Sixty growing male albino rats, weighing 43-57 grams, utilized in this study. The animals were divided into 3 groups; each of 20 rats: animals of group I served as control, animals of group II received 6 mg/kg body weight antimony trisulfide daily f...
