To perform high quality imaging for hydrogen nucleus 1H and nuclide different from the 1H.SOLUTION: A magnetic resonance imaging device of an embodiment includes static magnetic field generation means, a transmission and reception system, and collection means. The static magnetic field generation means applies a second static magnetic field in addition to a first static magnetic field being a reference. The transmission and reception system performs transmission and reception at a single frequency. The collection means collects magnetic resonance signal by using the transmission and reception system. The transmission and reception system performs the transmission and reception with a resonance frequency of the hydrogen nucleus in a state that the first static magnetic field is applied, and performs the transmission and reception with a resonance frequency of the nuclide different from the hydrogen nucleus in a state that the second static magnetic field is applied in addition to the first static magnetic field.SELECTED DRAWING: Figure 1 【課題】水素原子核１Ｈ及び１Ｈと異なる核種をそれぞれ対象として高画質に撮像を行うこと。【解決手段】実施形態に係る磁気共鳴イメージング装置は、静磁場発生手段と、送受信系と、収集手段とを備える。静磁場発生手段は、基準となる第１の静磁場に加え第２の静磁場を印加する。送受信系は、単一の周波数で送受信を行う。収集手段は、前記送受信系を用いて磁気共鳴信号を収集する。前記送受信系は、前記第１の静磁場が印加された状態で、水素原子核の共鳴周波数で送受信を行い、前記第１の静磁場に加え前記第２の静磁場が印加された状態で、前記水素原子核と異なる核種の共鳴周波数で送受信を行う。【選択図】図１
