    摘要： The present invention provides methods for passive visualisation of invasive devices by employing a hyperpolarised solution of a high T1 agent having a T1 value of at least 5 seconds at a field strength in the range of 0.001-5 T and a temperature in the range of 20-40° C. Devices and instruments particularly useful for being employed in the methods are also provided as well as use of the methods in imaging, surgery and therapy.

    摘要： A system and method are provided for imaging multiple substances, such as contrast agents and metabolites in vivo, with selective excitation frequencies. A first substance is excited with a frequency selective pulse, then a second substance is excited with another frequency selective pulse. The signals resulting from these pulses are acquired in an order reversed from the order in which the pulses were applied. In some embodiments, more than two substances may be imaged. The system and method thus provide for quick and efficient utilization of the magnetization of multiple substances for spectral-spatial imaging.

    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.
