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]
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]
Bio-FETs couple a transistor device with a bio-sensitive layer that can specifically detect bio-molecules such as nucleic acids and proteins. A Bio-FET system consists of a semiconducting field-effect transistor that acts as a transducer separated by an insulator layer (e.g. SiO 2) from the biological recognition element (e.g. receptors or probe molecules) which are selective to the target ...
Xenon isotope geochemistry uses the abundance of xenon (Xe) isotopes and total xenon to investigate how Xe has been generated, transported, fractionated, and distributed in planetary systems. Xe has nine stable or very long-lived isotopes. Radiogenic 129 Xe and fissiogenic 131,132,134,136 Xe isotopes are of special interest in geochemical ...
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.

Xenon-enhanced CT scanning is a method of computed tomography (CT scanning) used for neuroimaging in which the subject inhales xenon gas while CT images are made. [1] The method can be used to assess changes in cerebral blood flow in the period shortly after a traumatic brain injury , [ 1 ] or to detect or indicate the location of a stroke. [ 2 ]
