A magnetic resonance imaging apparatus includes a collection unit that applies a uniform static magnetic field to a subject and also applies a radio-frequency magnetic field and a gradient magnetic field to the subject in accordance with a predetermined pulse sequence to collect a magnetic resonance signal from the subject, an imaging unit that images the subject based on the magnetic resonance signal collected by the collection unit, a detection unit that detects a respiratory level of the subject, an informing unit that informs the subject of whether the detected respiratory level falls within an allowable range, and a unit that controls the collection unit and the imaging unit in such a manner that the magnetic resonance signal for imaging is collected and the subject is imaged based on the thus collected magnetic resonance signal for imaging when the detected respiratory level falls within the allowable range.
