In addition to a few percent of (99m)Tc pertechnetate less than 0.5% of disturbing radioactivity was found.

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).

PERTECHNETATE FROM THE ELUTION OF 99Mo/99m Tc GENERATOR. Ibrahim I. Technetium Tc-99m pertechnetate is a radiopharmaceutical diagnostic agent composed of an oxoanion with the chemical formula TcO4-.

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. The USP XXIII specifies that technetium radiopharmaceuticals contain no more than 0.15 microcuries of Mo-99 per millicurie of Tc-99m radiopharmaceutical at time of patient administration. Molybdenum breakthrough and expiration time for the Tc-99m must be determined for every elution from a Mo-99/Tc-99m generator. [99m Tc]pertechnetate ([99m Tc]TcO 4-) acts as an electrolyte tracer in such examinations.

• Separation of daughter Tc-99m from parent Mo-99 is usually accomplished by eluting a moly- Thyroid follicular cells can take up iodine and 99m Tc pertechnetate; however, only iodine is organified and stored (as thyroglobulin) in the lumen of thyroid follicles.
