Abstract

To preventing a deterioration in NMR signals due to a slice-leaned state, in executing a pulse sequence by the spin echo method, the inclination angle G2 of the slice gradient at the time of applying a 180° RF pulse P is made smaller than the inclination angle G1 of the slice gradient at the time of applying a 90° RF pulse R.
