Detection of Symptomatic Heterotopic Gastric Mucosa of the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy
… Mucosa of the Upper Esophagus using Tc-99m Pertechnetate Scintigraphy Heterotopic gastric mucosa of the upper esophagus (HGMUE) often referred to as an inlet patch, is an asymptomatic benign lesion. However, this inlet patch may cause esophageal ulceration and stricture, leading to symptoms …

Quantitative Pertechnetate Thyroid Scintigraphy and the Ultrasonographic Appearance of the Thyroid Gland in Clinically Normal Horses
… to salivary (T/S) ratio, percent dose uptake of pertechnetate and thyroid lobe volume were calculated. Echogenicity of thyroid lobes and presence of nodules were documented. The two groups were compared using appropriate parametric and nonparametic tests. Total T4 concentrations were …

Corrosion Behavior of Nuclear Waste Storage Canister Materials
… State. It is often found as highly oxidized pertechnetate (TeO4-) anions at these storage sites which also happen to be highly alkaline and contain a significant amount of nitrate. Theoretically, pertechnetate anions can act as electron acceptors and interact with the mild steel containers …

Application of radioisotope imaging and therapy in patients with breast carcinomas that express the sodium iodide symporter gene
… cancer. Results Twenty-four patients had a Tc99m Pertechnetate scan; 20 patients had their RNA analysed; 22 patients had IHC performed on their tumour samples. NIS was detected only in the control Graves thyroid RNA and paraffin embedded cells extracted from a NIS expressing cell line. Breast …

Effectiveness of Non-Chromate Inhibitors on Preventing Corrosion of Aluminum Alloys
… dissolution studies. The effectiveness of pertechnetate as a corrosion inhibitor for aluminum alloys has been investigated through radiometric adsorption studies. The effects of solution pH, electrode potential, and ion content in the supporting electrolyte have been studied and their …

Efficacy of single fixed dose of radioiodine (I-131) therapy in patients with hyperthyroidism at Groote Schuur Hospital
… documented. The images of their Tc-99m sodium pertechnetate thyroid scans were also retrieved and reprocessed. Results: The records of 409 patients treated between April 2010 and November 2017 were retrieved. 223 (63%) patients were referred by the endocrine clinic at Groote Schuur hospital …

Synthesis, characterization, and reactivity of low valent technetium phosphine complexes
… products. Chapter 2. The reduction of ammonium pertechnetate with bis(diphenylphosphino)methane (dppm), and with diphenyl-2-pyridyl phosphine (Ph2Ppy), has been investigated. The neutral Tc(II) complex, TcCl2(dppm)2, has been isolated from the reaction of (NH4)[TcO4] with excess dppm in …

Reaction condition effects on Re(VII) sorption kinetics at the zerovalent iron-water interface
… precipitation of the dominant risk driver, pertechnetate, 99Tc(VII)O4- to the sparing soluble 99Tc(IV). Some previous studies show that a variety of hazardous elements immobilized by slag can still remain mobile and leach out of the cement systems. Therefore, use of additional reducing …

Evaluation of Thyroid to Background Ratios in Hyperthyroid Cats
… data. The heart ROI correlated best to plasma pertechnetate activity (r = 0.70). % dose uptake correlated best to serum T4 (r = 0.74), followed by T:S ratio (r = 0.66), followed by the T:B ratio using the heart ROI (r = 0.59). Placing an ROI over the heart is the best method of quantifying …
