Abstract:129 Xe dissolution dynamic nuclear polarization (DNP) is a controversial topic. The gold standard technique for hyperpolarized xenon magnetic resonance imaging (MRI) is spin exchange optical pumping, which received FDA approval in 2022. Nevertheless, the versatility of DNP for enhancing the signal of any NMR active nucleus might provide new perspectives for hyperpolarized 129 Xe NMR/MRI. Initial publications about 129 Xe DNP underlined the increased complexity in the sample preparation and lower polarization … Show more
