(57) [Summary] [Purpose] By further devising the GRASE method, a plurality of images with a signal attenuation degree due to a difference in magnetic susceptibility as a parameter or a plurality of multi-contrast images can be simultaneously obtained. [Structure] Signals S1, S4, and S7 having the same time relationship from a 180 ° pulse have one K space, and signals S2, S5, and S8 having the same time relationship from a 180 ° pulse have another K space. The amount of phase encoding for each signal is determined so that the signals S3, S6, and S9 having the same time relationship from the .degree. |
