1. A method of imaging using magnetic resonance, the method comprising:
- administering hyperpolarized noble gas to a subject in a region to be imaged;
applying a magnetic field of a magnitude between about 0.0001 Tesla and about 0.1 Tesla to the subject at least in the region of the subject to be imaged;
detecting a spatial distribution of magnetic resonance signals of the hyperpolarized noble gas in the subject; and
producing a representation of the spatial distribution.

Abstract
A method of imaging using magnetic resonance includes administering hyperpolarized noble gas to a subject in a region to be imaged, applying a magnetic field of a magnitude between about 0.0001 Tesla and about 0.1 Tesla to the subject at least in the region of the subject to be imaged, detecting a spatial distribution of magnetic resonance signals of the hyperpolarized noble gas in the subject, and producing a representation of the spatial distribution.
