To avoid discontinuities between echoes from becoming large level differences in a k-space and to reduce artifacts generated in a reconstructed image due to the discontinuities in the k-space, an MRI apparatus of the present invention uses phase characteristics of multiple echoes to be collected after a single RF excitation to control an arrangement order in the k-space where the multiple echoes are arranged when a pulse sequence of the fast spin echo method that collects the multiple echoes using a spin flip after a single RF excitation is executed. The arrangement is controlled so that echoes with small phase errors between the echoes at least near the center of the k-space are adjacent to each other.
