摘要:
A magnetic resonance imaging system includes a static magnetic field generating section, a gradient magnetic field applying section, an RF pulse applying section, a sequence control section, a receiving section, and an imaging processing section. The sequence control section causes an RF pulse to excite magnetic resonance, causes at least one of the RF pulse and the gradient field to produce an initial magnetic resonance echo, applies a read gradient field to the imaging volume upon reception of the magnetic resonance echo, and inverts the read gradient field at least once to produce at least one magnetic resonance echo in addition to the initial magnetic resonance echo. The receiving section adds and averages data of a plurality of such magnetic resonance echoes or performs an addition or subtraction of the magnetic resonance echoes.
