Overview
Tc 99m pertechnetate is a versatile radiotracer taken up by thyroid and gastric mucosa and used in multiple diagnostic nuclear medicine studies.
Properties
Anionic pertechnetate is trapped by sodium iodide symporter expressing tissues and emits gamma photons for planar and SPECT imaging.
Uses
Used for thyroid uptake and scan, Meckel diverticulum detection in children, salivary gland imaging and some gastric emptying protocols.
Safety
Low radiation dose but follow pregnancy screening and local nuclear medicine safety procedures; consider thyroid blockade when indicated.
