Problem to be solved: to provide a magnetic resonance imaging device which lowers the tone of the subject during inspection without deteriorating image quality.Solution: a gradient magnetic field generating system 3 for generating a gradient magnetic field superimposed on the static magnetic field, a transmission system 5 for irradiating the subject with a high frequency magnetic field pulse, a receiving system 6 for detecting an echo signal emitted from the subject in response to the application of a high frequency magnetic field pulse, and generation of a gradient magnetic field by the gradient magnetic field generating system In a magnetic resonance imaging apparatus having a sequencer 4 that controls the detection of echo signals by irradiation of a high frequency magnetic field pulse by a transmission system and detection of an echo signal by a receiving systemThe measurement order is determined so as to alternately measure the echo signal of the k-space position where the sound pressure is relatively high and the echo signal of the k-space position where the sound pressure is relatively low.Diagram【課題】画質を劣化させることなく、検査時に被検体の感じる音を下げる磁気共鳴イメージング装置を提供する。【解決手段】静磁場に重畳する傾斜磁場を発生させる傾斜磁場発生系3と、被検体に高周波磁場パルスを照射する送信系5と、高周波磁場パルスの印加に応じて被検体より放出されるエコー信号を検出する受信系6と、傾斜磁場発生系による傾斜磁場の発生、送信系による高周波磁場パルスの照射及び受信系によるエコー信号の検出を制御するシーケンサ4を有する磁気共鳴イメージング装置において、所定のパルスシーケンスを実行するにあたり、音圧が相対的に高いk空間位置のエコー信号と音圧が相対的に低いk空間位置のエコー信号とを交互に計測するよう計測順序を決定する。【選択図】図1
