Magnetic resonance imaging apparatus

A magnetic resonance imaging apparatus, comprising:

• a data gathering unit configured to gather magnetic resonance data in a non-contrast manner by applying a first readout gradient pulse having a zero-order moment of 0 and a second readout gradient pulse having a zero-order moment of 0 and a first-order moment of a value different from a value of a first-order moment of the first readout gradient pulse to a region of interest including a fluid in motion wherein the first readout gradient pulse is a gradient pulse formed by adding to a pulse main body a flow dephasing pulse having a same polarity as the pulse main body, and the second readout gradient pulse is a gradient pulse formed only by the pulse main body;
• and
• an image generating unit configured to periodically arrange first magnetic resonance data read out with the first readout gradient pulse and second magnetic resonance data read out with the second readout gradient pulse in at least one of a phase encoding direction and a slice encoding direction in a k-space to generate k-space data and reconstruct the k-space data, and to generate an image in which a fluid image and a static part image surrounding fluid are spatially separated from each other.
