Abstract:
A magnetic resonance diagnosis apparatus comprising:means for applying an inversion pulse to the subject in a static magnetic field, in order to selectively suppress one of spins of nuclide contained in first molecule and spins of the same nuclide contained in second molecule on the basis of the difference in the longitudinal relaxation time, and applying an excitation pulse after a delay time corresponding to the time constant of longitudinal relaxation of one of the spins of the nuclide contained in the first molecule and the spins of the same nuclide contained in the second molecule from the inversion pulse;means for collecting MR signals from other one of the spins of the nuclide contained in the first molecule and the spins of the same nuclide contained in the second molecule; andmeans for obtaining at least one of resonance frequency data of the other one of the spins of the nuclide contained in the first molecule and the spins of the same nuclide contained in the second molecule, data corresponding to resonance frequency, magnetic field distribution data of the static magnetic field, and data corresponding to magnetic field distribution, on the basis of the MR signals.
