According to one embodiment, a magnetic resonance imaging apparatus includes an imaging condition setting unit and an imaging unit. The imaging condition setting unit is configured to set slice positions same as past slice positions to a same object and to set a table position of a bed with the object set to position a position representing a slice position designated out of the slice positions or a position representing a slice range designated out of the slice positions on a center of a magnetic field. The imaging unit is configured to acquire magnetic resonance data from the slice positions set for the object at the table position of the bed to generate image data corresponding to the slice positions based on the acquired magnetic resonance data.
