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.

It is not known whether Sodium Pertechnetate Tc 99m can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity.Sodium Pertechnetate Tc 99m should be given to pregnant women only if the expected benefits to be gained clearly outweigh the potential hazards.Ideally, examinations using radiopharmaceutical drug products - especially those elective in nature - of Can I take Sodium Pertechnetate Tc 99m while breastfeeding? Information in this record refers to the use of sodium pertechnetate Tc 99m as a diagnostic agent. The United States Nuclear Regulatory Commission states that breastfeeding should be interrupted temporarily after administration of sodium pertechnetate Tc 99m to a nursing mother. All patients had undergone Tc-99m pertechnetate and postablative I-131 scans.

Specificity of 99mTc Pertechnetate in Scintigraphic cells labeled in vivo with Technetium 99m by Gary.

A 41-year-old woman was referred to our department under the tentative diagnosis of primary hyperparathyroidism. Scintigraphy by thallium-201 chloride s … When a solution of sterile, non-pyrogenic, oxidant-free isotonic Sodium Pertechnetate Tc 99m Injection is added to the vial, Technetium TC 99M Pentetate Injection is formed. The product so derived is intended for intravenous injection within 6 hours of the time of reconstitution. Technetium-99m pertechnetate (99m Tc0 4) is obtained directly from the "molly" generator using saline as the eluting solution. This radiopharmaceutical is used for brain, thyroid, salivary gland, and stomach scanning.
