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.
[99m Tc]pertechnetate ([99m Tc]TcO 4-) acts as an electrolyte tracer in such examinations. Dynamic scans on anterior–posterior planar images have high time resolution, and the use of vitamin C stress test enables the evaluation of both accumulation in and secretion from the salivary glands [ 7 , 8 ].

Other chemical forms of 99m Tc do not exceed 5 percent of the total radioactivity. In this study, tetrofosmin whole-body scintigraphy was performed in 35 patients with evidence of thyroid diseases. All patients underwent laboratory evaluation of thyroid function as well as 99m Tc pertechnetate scan, thallium-201 (n=16) 99m Tc-methoxyisobutylisonitrile (MIBI) (n=19) whole-body studies. Dual Tracer technique with Tc‐99m pertechnetate and Tc‐99m tetrofosmin could be helpful in selecting nodules need surgical intervention. This technique can be used for convenient and rapid diagnostic evaluation of thyroid nodules non‐invasively. 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.

99m Tc-pertechnetate scan remains the most accurate test for the detection of ectopic thyroid tissue (Noussios et al., 2011; Fig. 11).Despite new molecular genetic insight into congenital hypothyroidism the 123 I or, preferably, 99m Tc-pertechnetate scan remains the most accurate test for the detection of ectopic thyroid tissue and the differential diagnosis between thyroid dysgenesis (60–70
The uptake of the pertechnetate anion - similar in chemical-physical characteristics to the iodide ion - in the thyroid parenchyma is mediated by the NIS (Sodium-Iodide Symporter). The pertechnetate ion is an oxoanion with the chemical formula TcO− 4. It is often used as a convenient water-soluble source of isotopes of the radioactive element technetium (Tc). In particular it is used to carry the 99m Tc isotope (half-life 6 hours) which is commonly used in nuclear medicine in several nuclear scanning procedures.

technetium tc-99m sodium pertechnetate Any 99m Tc that is not in the form of pertechnetate is regarded as a radiochemical impurity. An impurity that is sometimes observed in samples eluted from generators is hydrolyzed reduced technetium. This material occurs as an insoluble "colloid", that if injected, will localize in the liver and spleen. 2021-03-31 · [99m Tc]pertechnetate ([99m Tc]TcO 4-) acts as an electrolyte tracer in such examinations.
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.

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. 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. Tc-99m pertechnetate and I-123 were used to perform thyroid scanning in 122 patients with history or clinical evidence of thyroid disease.
