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]

At standard temperature and pressure, pure xenon gas has a density of 5.894 kg/m 3, about 4.5 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [52] As a liquid, xenon has a density of up to 3.100 g/mL, with the density maximum occurring at the triple point. [ 53 ]
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]
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]
The biosensor reader device connects with the associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. [5] This sometimes accounts for the most expensive part of the sensor device, however it is possible to generate a user friendly display that includes transducer and ...
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 ...
In addition to compounds where xenon forms a chemical bond, xenon can form clathrates—substances where xenon atoms or pairs are trapped by the crystalline lattice of another compound. One example is xenon hydrate (Xe· 5 + 3 ⁄ 4 H 2 O), where xenon atoms occupy vacancies in a lattice of water molecules. [32] This clathrate has a melting ...
