A Magnetic Resonance Imaging apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to execute a pulse sequence to acquire data from an image taking region after applying a pre-pulse in synchronization with a predetermined electrocardiographic waveform of the subject. The processing circuitry is configured to monitor recovery of longitudinal magnetization by acquiring data from a monitor region that is different from the image taking region, by using timing linked with the timing with which the pre-pulse is applied. The processing circuitry is configured to control execution of the pulse sequence on the basis of a signal value of the data from the monitor region.
