Abstract: According to one embodiment, a magnetic resonance imaging apparatus includes a processing circuit. The processing circuit is configured to predict, based on an imaging sequence of magnetic resonance imaging and a relationship between a driving frequency of a gradient field coil and one of a magnet internal pressure and a magnet temperature of a static field magnet, the one of the magnet internal pressure and the magnet temperature at the time of execution of the imaging sequence, adjusts the imaging sequence based on a prediction result, and execute the adjusted imaging sequence.
