Abstract
A magnetic resonance imaging apparatus includes an imaging unit and a compensation unit. The imaging unit acquires image data by imaging with applying a pre-pulse for controlling a contrast. The compensation unit suppresses a remanent magnetic field having an intensity according to a slice position. The remanent magnetic field is at an application timing of the pre-pulse and due to an eddy current generated by at least one gradient magnetic field applied before applying the pre-pulse.
