<p><P>PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus which can perform high precision cardiac muscle perfusion imaging by making dynamic imaging relatively correspond to a cardiac time-phase without the necessity for a patient to hold his/her breath. <P>SOLUTION: Upon myocardium perfusion imaging, the variation of position in the dynamic time-phase direction due to a respiratory body motion is detected, and the slice excitation position and the data collection position are made to follow up the body motion according to the variation. The variation of cardiac time-phase is measured, TI waiting time and a flip angle of saturation pulse are suppressed to match the variation, and the time-phase of dynamic imaging is made to relatively correspond to the cardiac time-phase to schedule an imaging condition corresponding to a pattern of cardiac pulse variation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
