Hyperpolarized gas MRI, also known as hyperpolarized helium-3 MRI or HPHe-3 MRI, is a medical imaging technique that uses hyperpolarized gases to improve the sensitivity and spatial resolution of magnetic resonance imaging (MRI). This technique has many potential applications in medicine, including the imaging of the lungs and other areas of ...
Hyperpolarized 129 Xe gas magnetic resonance imaging is a medical imaging technique used to visualize the anatomy and physiology of body regions that are difficult to image with standard proton MRI. In particular, the lung, which lacks substantial density of protons, is particularly useful to be visualized with 129 Xe gas MRI. This technique ...
Hyperpolarization machines are currently being used to develop hyperpolarized xenon gas that is used as a visualization agent for the lungs. Xenon-129 is a safe inert noble gas that can be used to quantify lung function. With a single 10-second breath hold, hyperpolarized Xenon-129 is used with MRI to enable 3-dimensional lung imaging.

Traditional MRI generates poor images of lung tissue because there are fewer water molecules with protons that can be excited by the magnetic field. Using hyperpolarized gas an MRI scan can identify ventilation defects in the lungs. Before the scan, a patient is asked to inhale hyperpolarized xenon mixed with a buffer gas of helium or nitrogen ...
Hyperpolarized carbon-13 MRI is a functional medical imaging technique for probing perfusion and metabolism using injected substrates. It is enabled by techniques for hyperpolarization of carbon-13 -containing molecules using dynamic nuclear polarization and rapid dissolution to create an injectable solution.
Jay-Z is accused in a lawsuit of raping a 13-year-old girl with fellow music mogul Sean “Diddy” Combs. The lawsuit was first filed in October but did not list Jay-Z, whose given name is Shawn ...
Carbon dioxide sequestration involves capturing the gas from industry and storing it underground. In June of last year, Louisiana officials House committee address citizen concerns over carbon ...
