Abstract:
A magnetic resonance apparatus comprising:means for applying an excitation pulse and refocusing pulse to spins of a first nuclide and for applying a return pulse to the spins of the first nuclide at an echo time of the spins of the first nuclide;means for applying a plurality of inversion pulses having different frequency bands from each other to spins of a second nuclide spin-spin coupled to the first nuclide at an interval between the excitation pulse and the return pulse so as to produce a polarization transfer from the spins of the first nuclide to the spins of the second nuclide and for applying an excitation pulse to the spins of the second nuclide simultaneously with or after the return pulse; andmeans for, after the excitation pulse applied to the spins of the second nuclide, receiving from the spins of the second nuclide a magnetic resonance signal enhanced by the polarization transfer.
