ABSTRACT:
In certain embodiments, methods of the present invention obtain NMR spectroscopy signal data that corresponds to the behavior of the polarized129Xe at a selected site(s) in selected environments in vivo. The gas exchange signal data can be used to evaluate: (a) the thickness of a barrier, such as a membrane, lining, wall or width of a lumen; (b) the operational condition or function of a membrane, body system or portion thereof; (c) cerebral perfusion; 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 disorder or disease, and/or methods for monitoring the efficacy of therapeutics administered to subject to treat a disorder or disease.
