It reacts with electrophilic chlorides including acyl chlorides, sulfur chlorides, and phosphorus chloride. Sodium fluoride has a variety of specialty chemical applications in synthesis and extractive metallurgy. ![]() Additionally the annihilation photons produced by decay of 18F have a high energy of 511 keV compared to the 140 keV photons of 99mTc. ![]() In particular it has a high and rapid bone uptake accompanied by very rapid blood clearance, which results in a high bone-to-background ratio in a short time. However fluorine-18 is generally considered to be a superior radiopharmaceutical for skeletal imaging. Fluorine-18 has a half-life of 110 min, which requires it to be used promptly once produced this logistical limitation hampered its adoption in the face of the more convenient technetium-99m-labelled radiopharmaceuticals. Relative to conventional bone scintigraphy carried out with gamma cameras or SPECT systems, PET offers more sensitivity and spatial resolution. In medical imaging, fluorine-18-labelled sodium fluoride ( USP, sodium fluoride F18) is one of the oldest tracers used in positron emission tomography (PET), having been in use since the 1960s. This supplementation does not appear to be effective even though sodium fluoride increases bone density, it does not decrease the risk of fractures. Osteoporosis įluoride supplementation has been extensively studied for the treatment of postmenopausal osteoporosis. Although sodium fluoride is used to fluoridate water and is the standard by which other water-fluoridation compounds are gauged, hexafluorosilicic acid (H 2SiF 6) and its salt sodium hexafluorosilicate (Na 2SiF 6) are more commonly used additives in the United States. The fluoride enhances the strength of teeth by the formation of fluorapatite, a naturally occurring component of tooth enamel.
