Xenon Xe 129 hyperpolarized, sold under the brand name Xenoview, is a hyperpolarized contrast agent indicated for use with magnetic resonance imaging (MRI) for evaluation of lung ventilation, and approved for people aged twelve years of age and older. [4] [5] It was approved for medical use in the US in December 2022. [6]

Because of its scarcity, xenon is much more expensive than the lighter noble gases—approximate prices for the purchase of small quantities in Europe in 1999 were 10 €/L (=~€1.7/g) for xenon, 1 €/L (=~€0.27/g) for krypton, and 0.20 €/L (=~€0.22/g) for neon, [67] while the much more plentiful argon, which makes up over 1% by volume ...
Qing et al. used the Hierarchical IDEAL algorithm to image all three resonances of xenon in a single breath. The 1-point Dixon strategy has also been successful and may be more robust against the short T2* of the dissolved-phase 129 Xe signal. This technique was also recently used to image all three resonances of xenon in a single breath. [43]
Biosensors International also licenses its proprietary drug-eluting stent technologies to other medical device companies and specialty stent providers, including Terumo, Devax, Inc., and Xtent, Inc. Biosensors International Group has a joint-venture in Hong Kong listed as Shandong Weigao to market and distribute coronary stents in China. [1]
The xenonium ion, XeH +, is an onium compound, consisting of protonated xenon. Although the existence of the xenonium salts has not been proven, the isolated XeH + ion is known. [ 2 ] Salts of the fluoroxenonium ion, XeF + , are known to exist, for instance fluoroxenonium pentafluoroplatinate (XeFPtF 5 ), more commonly known as xenon ...
Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
Electrochemical aptamer-based (E-AB) biosensors is a device that takes advantage of the electrochemical and biological properties of aptamers to take real time, in vivo measurements. An electrochemical aptamer-based (E-AB) biosensor generates an electrochemical signal in response to specific target binding in vivo [ 3 ] The signal is measured ...
