- 摘要：
To provide an MRI apparatus suppressing an artefact based ON a false echo signal without applying a crusher gradient magnetic field pulse with a large amount of application.
SOLUTION: The MRI apparatus includes a measurement control means for controlling the measurement of an echo signal by applying a plurality of RF pulses and a plurality of gradient magnetic field pulses to a subject and ON the basis of a prescribed pulse sequence. The plurality of gradient magnetic field pulses include the pair of crusher gradient magnetic field pulses equal in the amounts of application and which are applied before/after at least one RF pulse. The measurement control means controls the application of the pair of crusher gradient magnetic field pulses in response to the polarity of the prescribed gradient magnetic field pulse.
