A magnetic resonance imaging apparatus according to an embodiment includes a specifying unit and an acquiring unit. The specifying unit specifies, on a basis of a detection result of target sites of a subject detected from an image on which the target sites are visualized, a first region and a second region which is different from the first region on the image. The acquiring unit acquires data of the second region by using an imaging condition which is different from an imaging condition on an imaging slice and used for acquiring data of the first region.
