Technetium-99m complexes with steroid-2-aminooxyethyliminodiacetic acid conjugates.
Conjugates of 2-aminooxyethyliminodiacetic acid with estrone, testosterone, epiandrosterone, 17-alpha-hydroxy-progesterone and progesterone were synthesized and their complexes with Tc-99m were successfully prepared in good yields, which indicated the agent to be promising for metal-labeling of biomolecules and related substances containing one or more carbonyl groups. The biodistribution and s...
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...
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 کاملElectrophoretic analysis of different technetium-99m (SnCl2) methylene diphosphonate complexes.
Technetium-99m MDP was prepared from MDP kits from several different sources. The resulting [99mTc]MDP preparations were analyzed by electrophoresis. The results demonstrated the presence of at least four different 99mTc complexes in these preparations. Modified kit preparations were analyzed to show the effects of concentration and pH on formation of the impurities. The electrophoresis results...
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...
