Abstract:
1. A magnetic resonance imaging device comprising; magnetostatic field generating unit that generates magnetostatic field in an imaging space in which an examinee is disposed; gradient magnetic field generating unit that generates gradient magnetic field in the imaging space; high-frequency magnetic field generating unit that generates high-frequency magnetic field in the imaging space; receiving unit that detects a nuclear magnetic resonance signal generated from the examinee; image creating unit that generates an image by using the nuclear magnetic resonance signal detected by the receiving unit; and control unit that controls the gradient magnetic field generating unit, the high-frequency magnetic field generating unit and the receiving unit according to a predetermined pulse sequence that contains wherein the unnecessary material suppressing sequence unit generates at least two RF magnetic field pulses such that an application interval between the two or more high-frequency magnetic field pulses or an application interval between the last high-frequency magnetic field pulse of the two or more high-frequency magnetic field pulses and a first high-frequency magnetic field pulse in the main imaging sequence unit is set so as to make the longitudinal magnetization of the unnecessary material under application of the first high-frequency magnetic field pulse in the main imaging sequence unit be same as a desired value.
