The compound (n-Bu4N)2Tc2Br8 was prepared by the metathesis of (n-Bu4N)2Tc2Cl8 with HBr (g) in dichloromethane and characterized by X-ray absorption fine structure spectroscopy and UV-vis spectroscopy. Analysis of the data gives a Tc-Tc distance of 2.16(1) A and a Tc-Br distance of 2.48(1) A. The Tc(III) oxidation state was inferred by the position of the edge absorption, which reveals a shift ...

background: local ablative treatments play an important role for patients who cannot be treated surgically. radiofrequency ablation is a well-established alternative to surgical treatment of thyroid nodules, however it also has disadvantages. microwave ablation (mwa) is a new minimally invasive treatment promising several improvements. the aim of this retrospective study was to evaluate the eff...

we report here a rare case of lateral ectopia of thyroid without orthotopic thyroid tissue in an indian teenager, who was referred to our department for a thyroid scintigraphy. technetium pertechnetate (99mtco4- ) scan showed uptake in laterally placed soft tissue structure along with functioning thyroid tissue in high anterior midline neck region in line with thyroglossal tract. there is no up...

Aim: To compare the ARFI elastographic and scintigraphic quantitative data obtained from thyroid gland to evaluate diagnostic value of measurements in autoimmune diseases.
 Material Method: In study a total 61 patients (41 women, 20 men) including 24 Graves’ disease, 15 Hashimoto disease 22 control subjects. The mean age was 33.9±10.9 years. Patients with nodules were not included study. T...

Primary and secondary gastrointestinal tumors have been identified using sheep immunoglobulin G antibody to carcinoembryonic antigen radiolabeled with 131I. 99mTc-pertechnetate and 99mTc-human serum albumin were used to identify tissue spaces and blood pool and to facilitate external substraction imaging. In 13 patients with tumors, 4 of 5 primary sites and 8 of 11 secondary sites were successf...

The uptake of Tc-99m pertechnetate and Co-57 bleomycin and the ultrastructure of small blood vessels were studied in 10 cases of meningioma. When thin sections of 120 contact areas between adjacent endothelial cells were examined, 92% of the intercellular contacts contained one to three punctate tight junctions. Freeze fracture preparations revealed fascia occludens with one to four sealing str...
