Le technétium possède une trentaine d'isotopes, tous radioactifs, dont les masses générale, le technétium se trouve sous forme d'anion pertechnétate.

3 Negative remnant ^99mTc-pertechnetate uptake predicts excellent response to radioactive iodine therapy in low- to intermediate-risk differentiated thyroid cancer patients who have undergone total thyroidectomy. Pertechnetate can be reduced by H 2 S to give Tc 2 S 7. Pertechnetate is also reduced to Tc(IV/V) compounds in alkaline solutions in nuclear waste tanks without adding catalytic metals, reducing agents, or external radiation. Reactions of mono- and disaccharides with 99m TcO 4 − yield Tc(IV) compounds that are water-soluble.

PERTECHNETATE FROM THE ELUTION OF 99Mo/99m Tc GENERATOR. Ibrahim I., Zulkifli H., Bohari Y., Zakaria I. and Wan Hamirul B.W. K. Medical Technology Division, Agency Nuclear Malaysia, 43000 Kajang, Selangor, Malaysia. Abstract Radioisotope Tc-99m is widely used for variety of nuclear medicine diagnostic procedures. For Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.

The authors have developed a method to estimate the 24-hour sodium iodide thyroid uptake based on a 5-minute Tc-99m pertechnetate thyroid uptake using the equation: Estimated Iodide Uptake = 17.72*In(Pertechnetate Uptake) + 30.40. This estimation has a correlation coefficient of 0.90.

The use of 123 I-iodide is restricted to studies that require iodide organification, as in cases of congenital dyshormonogenic hypothyroidism and organification defects in autoimmune chronic thyroiditis Technetium 99m sodium pertechnetate Dose in Nasolacrimal drainage system imaging: Dacryoscintigraphy (ophthalmic instillation with a micropipette or similar method): Maximum: 0.1 mCi (3.7 MBq) Technetium TC 99m sodium pertechnetate Dose in Salivary gland imaging: IV: 1 to 5 mCi (37 to 185 MBq) Tc-99m pertechnetate and I-123 were used to perform thyroid scanning in 122 patients with history or clinical evidence of thyroid disease. Thyroid scans were abnormal in all patients, while thyroid palpation was abnormal in all but 19. Technetium Tc-99m pertechnetate Accession Number DB09314 Description. Technetium Tc-99m pertechnetate is a radiopharmaceutical diagnostic agent composed of an oxoanion with the chemical formula TcO4-. Pertechnetate has a wide variety of uses within nuclear medicine as it distributes within the body to a similar extent as iodine.

Sterile, nonpyrogenic isotonic solutions of Sodium Pertechnetate Tc 99m can be obtained conveniently by periodic aseptic elution of the generator. These solutions should be clear, colorless, and free from any particulate matter. The carrier-free solution may be used as is, or diluted to the proper concentration.

Sodium Pertechnetate Tc-99m injection is also indicated in • Adults for: Salivary Gland Imaging and Nasolacrimal Drainage System Covidien 99m tc pertechnetate 99m Tc Pertechnetate, supplied by Covidien, used in various techniques. Bioz Stars score: 90/100, based on 6 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and more Sodium pertechnetate Tc 99m solutions which contain an oxidizing agent or saline solutions containing preservatives are not suitable for use in the preparation of Technescan HDP Tc 99m. Contents of the vial are intended only for use in the preparation of Technetium Tc 99m Oxidronate and are NOT to be administered directly to the patient. Pertechnetate Tc 99m is administered by direct instillation aseptically into the bladder via a urethral catheter, following which the catheter is flushed with approximately 200 mL of sterile saline directly into the bladder. Technetium-99m pertechnetate imaging in diagnosis of Meckel's diverticulum. Abdominal imaging after intravenous injection of 99mTc per- technetate is a Pour la scintigraphie thyroïdienne, la scintigraphie des glandes salivaires, l' identification de muqueuse gastrique ectopique, la solution de pertechnétate ( 99mTc) Pour ce faire, on injecte une quantité ténue de matériel radioactif, ici le technétium 99m, soit sous forme soluble dans l'eau comme l'anion pertechnétate TcO –4, Technetium 99m pertechnetate (99mTcO4−) is a useful radioactive label for thyroid scanning.

Pertechnetate has a wide variety of uses within nuclear medicine as it distributes within the body to a similar extent as iodine. TECHNETIUM Tc 99m GENERATOR for the Production of Sodium Pertechnetate Tc 99m DESCRIPTION: The Technetium Tc 09m Generator is prepared with fission produced Molybdenum Mo 99 absorbed on alumina in a lead-shielded column and provides a means for obtaining sterile pyrogen-free solutions of Sodium Pertechnetate Tc 99m in sodium chloride injection.
