Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes a phase image generating unit, an image value acquisition unit and a frequency shift calculation unit. The phase image generating unit executes a sequence including an application of a bipolar gradient pulse and thereby generates a first phase image. The image value acquisition unit acquires an image value of the first phase image. The frequency shift calculation unit determines an amount of frequency shift per unit amount of gradient magnetic field based on magnetic field strength of the bipolar gradient pulse and on the image value of the first phase image.
