Abstract
A magnetic resonance imaging apparatus which executes an imaging sequence for obtaining, as imaging data, magnetic resonance signals each generated from a spin excited at a subject within a static magnetic field space and produces an image about the subject, based on the imaging data obtained by the execution of the imaging sequence, includes a scan section which executes the imaging sequence and executes, before the execution of the imaging sequence, a preparation sequence for transmitting preparation pulses to the subject in such a manner that signal intensities of the magnetic resonance signals differ according to the velocities of spins moved in the subject, wherein the scan section sequentially transmits, as the preparation pulses, a first RF pulse, a second RF pulse, a third RF pulse and a fourth RF pulse respectively to the subject, wherein the scan section transmits a first crusher gradient pulse constituted of a pair of gradient pulses to the subject in such a manner that a point of time at which an RF pulse is transmitted as the second RF pulse is interposed at a time base, wherein the scan section transmits a second crusher gradient pulse constituted of a pair of gradient pulses to the subject in such a manner that a point of time at which an RF pulse is transmitted as the third RF pulse is interposed at the time base, and wherein the scan section transmits a killer gradient pulse to the subject after the transmission of the fourth RF pulse.
