Hyperpolarization is the nuclear spin polarization of a material in a magnetic field far beyond thermal equilibrium conditions determined by the Boltzmann distribution. It can be applied to gases such as 129Xe and 3He, and small molecules where the polarization levels can be enhanced by a factor of 104-105 above thermal equilibrium levels. Hyperpolarized noble gases are typically used in magnetic resonance imaging (MRI) of the lungs.Hyperpolarized small molecules are typically used for in vivo metabolic imaging. For example, a hyperpolarized metabolite can be injected into animals or patients and the metabolic conversion can be tracked in real-time. Other applications include determining the function of the neutron spin-structures by scattering polarized electrons from a very polarized tar

  • In der Physik versteht man unter Hyperpolarisation eine geordnete Ausrichtung von Kernspins in einer Materialprobe weit über das thermische Gleichgewicht hinaus.
  • Гиперполяризация — поляризация ядерных спинов веществ далеко за пределами теплового равновесия. Гиперполяризованные благородные газы обычно используются при магнитно-резонансной томографии лёгких. Уровень поляризации 129Xe и 3He может в 104—105 раз превышать уровень теплового равновесия. Методы гиперполяризации: * спин-обменная оптическая накачка; * оптическая накачка с обменом метастабильностью; * динамическая поляризация ядер (ДПЯ); * индуцированная параводородом поляризация ядер (ИППЯ); * усиление сигнала в результате обратимого обмена.
