Preparation and Characterisation of Technetium Metal and Technetium-ruthenium Alloys
Technetium metal and Tc-Ru alloys were characterised to build a database of the Tc metal target for transmutation. The lattice parameters of Tc-Ru alloys including Tc and Ru metals measured by X-ray diffraction decrease with increasing Ru concentration. The thermal conductivity of Tc-Ru alloys including Tc and Ru metals was determined by the thermal diffusivity measured by the laser flash metho...
متن کاملtechnetium-99m subtraction scanning
Solitary parathyroid adenomas were correctly located before surgery in 20 out of 21 cases by using 20lmTl and 99mTc in a subtraction technique. The technique was not useful in identifying hyperplastic parathyroid glands. The technique is recommended as a useful procedure before surgery for primary hyperparathyroidism.
متن کاملTechnetium-99m Ceftizoxime Kit Preparation
The aim of this work was to prepare a kit of Tc-ceftizoxime (Tc-CFT), with stability and biological activity preserved, able to identify a septic focus (E. coli) in the experimental infection model in rats. The preparation of the CFT kit involved the use of lyophilized solutions containing the antibiotic ceftizoxime and the sodium dithionite reducing agent (6.0 mg/mL). After lyophilization, the...
متن کاملApplication of electron microscopy in the observation of technetium and technetium dioxide nanostructures.
Transmission electron microscopy (TEM) was applied to characterize the microstructure of Tc metal and technetium dioxide synthesized by the decomposition of NH(4)TcO(4). The morphology of the Tc metal and well-resolved TcO(2) particles were characterized using bright-field TEM and scanning TEM modes. Structural characterization of these two samples using high-resolution (HR) TEM was successfull...
متن کاملNUCLEAR PHARMACY Rapid Quality Control of Technetium-99m-2-Methoxy Isobutyl Isonitrile (Technetium-99m-Sestamibi)
Objective: Technetium-99m-sestamibi (-1"'Tc-MIBI) is a radiopharmaceutical imaging agent useful for assessing myocardial perfusion. We present a simple, rapid and accurate SepPak® method to confirm the radiochemical purity of "'Tc-MIBI. Methods: Technetium-99m-MIBI preparations of high (>95%), intermediate (83-90%) and low (25-43%) radiochemical purity were evaluated by the recommended thinlaye...
