Abstract
The present invention aims to prevent the influence of a variation in residual magnetization due to a change in gradient or gradient magnetic field pulse. In an FSE sequence, reset pulses gys1j and gysrj each having amplitude equal to the maximum amplitude used in a phase axis are inserted into the phase axis before and behind an inversion pulse Pj.
