1-23. (canceled)
A method for performing a magnetic resonance protocol comprising:
- a) providing a magnetic resonance device including (i) a main magnet for providing a background magnetic field along a first direction, (ii) at least one radio-frequency coil, and (iii) at least one gradient coil that can be controlled to define at least one region of interest;
- b) defining the region of interest using the at least one gradient coil;
- c) introducing an agent wherein one or more nuclei have been hyperpolarized into the region of interest;
- d) inverting the vector direction of the polarization of the hyperpolarized nuclei to be at least partially anti-parallel to the direction of the magnetic field of the magnetic resonance device;
- e) inducing electromagnetic feedback between the nuclear magnetization of the hyperpolarized nuclei and the at least one nearby resonant coil to cause the vector direction of the nuclear magnetization to rotate to a desired angle with respect to the first direction of the background magnetic field to generate at least one electromagnetic pulse of transverse magnetization;
- and
- f) detecting the pulse of transverse magnetization with the at least one radio-frequency coil.
