Abstract: Techniques for deuterium metabolic imaging (DMI) are provided. According to some aspects, metabolic imaging techniques are described in which deuterium (i.e., 2H)-labeled molecules are detected to assess metabolic processes. These techniques may have an improved spatial resolution compared to conventional techniques, and may provide the ability to determine metabolic information on a voxel-by-voxel basis to form a metabolic image of an imaged volume.

Abstract: One aspect of the present disclosure relates to a method or determining location(s) at which at least one magnetic article is to be positioned during a magnetic resonance imaging procedure of at least one subject. A magnetic field Bo is applied to a region that includes the at least one subject and does not include the at least one magnetic article. First magnetic resonance information about the region in response to the applied magnetic field BO is received. The first magnetic resonance information relates at least in part to one or more magnetic field inhomogeneities in the region. Based at least in part on the first magnetic resonance information, at least one first location proximate the at least one subject at which at least one paramagnetic article and/or diamagnetic article is to be positioned is determined, so as to at least partially compensate for the one or more magnetic field inhomogeneities.

Abstract: In another aspect, the present invention relates to a method for NMR measurements of an arbitrarily shaped region of interest of a living subject. In one embodiment, the method comprises the steps of applying a broad bandwidth of RF pulses to the arbitrarily shaped region of interest to obtain a corresponding spectrum, wherein substantially entire range of chemical shifts in the spectrum is excited from the arbitrarily shaped region of interest, interleaving a plurality of radial k-lines in radial k-space per excitation with non-selective refocusing pulses and obtaining spatial localization for the spectrum of the arbitrarily shaped region of interest.
