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

  • data storage configured to store, as preset MRI sequence controlling information, a first time and a second time,the first time defining elapsed time since a non-selective first RF (radio frequency) pulse until start of MR signal acquisition,the second time defining elapsed time since a selective second RF pulse applied to a labeling region until the start of MR signal acquisition,the second time also being a time required for a liquid present in the labeling region at a timing of the second RF pulse to reach peripheral blood vessels in an imaging region,the first time also being a time for longitudinal magnetization components of a background tissue to become substantially zero, the background tissue being in the imaging region and being other than a target of interest labeled by the selective second RF pulse,the first time and the second time being configured to be different according to a purpose of imaging to be performed by the preset MRI sequence controlling information;

    image condition setting circuitry configured to display preset-able MRI sequence controlling information to a user;

    sequence controlling circuitry configured to (a) set timings of the first RF pulse and the second RF pulse, based on preset information chosen by the user among information displayed by the image condition setting circuitry and (b) acquire magnetic resonance signals in the imaging region after a given time has passed since an RF pulse was applied to the labeling region; and

    image generating circuitry configured to generate an image using the magnetic resonance signals.
