    摘要: The present invention relates to methods of performing Nuclear Magnetic Resonance (NMR) spectroscopy adapted for a hyperpolarized sample. The methods comprise the steps of hyperpolarizing a sample using DNP, wherein at least a portion of the NMR active nuclei receives hyperpolarization; performing NMR spectroscopy on the sample with the use of sequences of rf-pulses, wherein the pulse sequences comprises at least two rf-pulses, either on the same nuclei or on different nuclei, and wherein the pulse sequence is adapted for a hyperpolarized sample; and analyzing at least two of the NMR spectra to obtain a characterization of the sample, or to obtain an interim result to be used in the NMR spectroscopy step.

    摘要: In certain embodiments, methods of the present invention obtain dynamic data sets of an NMR spectroscopy signal of polarized 129Xe in a selected structure, environment, or system. The signal data can be used to evaluate: (a) the physiology of a membrane or tissue; (b) the operational condition or function of a body system or portion thereof (when at rest or under stimulation); and/or (c) the efficacy of a therapeutic treatment used to treat a diagnosed disorder, disease, or condition. Thus, the present invention provides methods for screening and/or diagnosing a respiratory, cardiopulmonary disorder or disease such as chronic heart failure, and/or methods for monitoring the efficacy of therapeutics administered to subject to treat the disorder or disease.

    摘要: The present invention relates to devices and methods for melting a solid polarised sample while retaining a high level of polarisation. In an embodiment of the present invention a sample is polarised in a sample-retaining cup in a strong magnetic field in a polarising means in a cryostat and then melted inside the cryostat by melting means such as a laser connected by an optical fibre to the interior of the cryostat.
