ABSTRACT:
A magnetic resonance imaging device includes control means for controlling receiving means according to a predetermined pulse sequence that includes an unnecessary material suppressing sequence unit for suppressing a signal from an unnecessary material which is not a measurement target, and a main imaging sequence unit for measuring a nuclear magnetic resonance signal used to create an image of an examinee. The unnecessary material suppressing sequence unit generates at least two or more high frequency magnetic field pulses so that the longitudinal magnetization of the unnecessary material is made spatially uniform in the imaging space under application of a first high frequency magnetic field pulse in the main imaging sequence unit.
