Abstract:
A magnetic resonance imaging method comprising the steps of applying a static magnetic field, gradient magnetic field and RF magnetic field to an object to be examined according to a predetermined pulse sequence, causing nuclear magnetic resonance (NMR) in nuclear spins within a given region of the object, measuring NMR signals caused by the NMR and displaying images produced using the measured signals,wherein a plurality of time-series NMR signal groups are obtained, on an individual image basis, for the same region of the object, one of the obtained NMR signal group is defined as standard data, a plurality of subtracted NMR signal groups are produced by performing subtraction between the standard NMR signal group and each of the other NMR signal groups, the subtracted NMR signal groups are subjected to addition operation, a subtracted NMR signal group obtained by the addition operation is reconstructed and displayed as an image.
