1. A magnetic resonance imaging (MRI) apparatus comprising:

  • MRI processing circuitry configured todivide, when performing a data acquiring process at a plurality of different timings by varying a waiting period until starting the data acquiring process after applying an RF wave to label fluid flowing into an imaging region of a patient, the plurality of different timings into at least two temporal ranges of timings; and

    perform the data acquiring process at a timing included in a first range of the temporal ranges by using a first readout sequence and perform the data acquiring process at a timing included in a second range of the temporal ranges by using a second readout sequence that is different from the first readout sequence in terms of one or both of a type of sequence and an imaging condition,wherein the processing circuitry is configured to change, when detecting that the labeled fluid has reached a predetermined position in the imaging region, the readout sequence used for performing the data acquiring process from the first readout sequence to the second readout sequence.
