In multi-echo imaging, in imaging in which pulses other than a 180° pulse are included in refocus RF pulses, a high-quality image in which the intended contrast is emphasized is obtained by reducing unnecessary contrast. Therefore, imaging parameters are adjusted so as to reduce the unnecessary contrast. The adjustment is performed so that, for echo signals from tissues having the same relaxation time to cause intended contrast among echo signals from a plurality of tissues having different relaxation times, the difference between the signal strengths of echo signals to determine the contrast, such as echo signals at the k-space center, is reduced. Imaging parameters to be adjusted include a repetition time, the FA of a DE pulse, the FA of a saturation pulse, the application timing of the saturation pulse, the application strength of a gradient magnetic field in a recovery period, application timing, and the like.
