Abstract:
1. A magnetic resonance imaging apparatus comprising: a static magnetic field forming unit which forms a static magnetic field in a space in which a subject is held; a transmission unit which transmits a plurality of inversion RF pulses to the subject lying in the static magnetic field plural times within one repetition time after transmission of one excitation RF pulse thereby to excite spins of the subject; a gradient magnetic field application unit which applies a gradient magnetic field to the subject and encodes magnetic resonance signals from the spins excited by the inversion RF pulses; a data acquisition unit which acquires the magnetic resonance signals encoded by the gradient magnetic field; and an image generation unit which generates an image of the subject, based on the magnetic resonance signals acquired by the data acquisition unit, wherein the gradient magnetic field application unit applies velocity encode gradient pulses inverted to one another in polarity to the subject within transmission interval times of the RF pulses transmitted to the subject.
