Abstract
In MRI using an SE-based pulse sequence, an object is to suppress flow artifacts and acquire a flow artifact-free image regardless a velocity or a direction of blood flow. A pair of gradient magnetic field pulses are applied before and after a 180-degree pulse of the SE-based pulse sequence, and a plurality of times of imaging are performed using varying intensities of the pair of gradient magnetic field pulses. Image reconstruction is performed by performing a Fourier transformation on measurement data obtained through the plurality of times of imaging in an axial direction of the intensities of the gradient magnetic field pulses, that is, a velocity encoding direction. As a result, images can be separated for each velocity of a stationary tissue and a non-stationary component included in tissues, and an image of spins with a velocity of zero, that is, a flow artifact-free image of the stationary tissue, can be obtained.
