| 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.
