Abstract
A magnetic resonance imaging apparatus according to an embodiment includes sequence controlling circuitry and image generating circuitry. The sequence controlling circuitry acquires magnetic resonance signals in an imaging region. The image generating circuitry generates an image. The sequence controlling circuitry sets timings of RF pulses such that a first time and a second time are different. Here, the first time is a time since an irradiation of a first RF pulse without selection of region until a start of acquisition. The second time is a time since an irradiation of a second RF pulse with selection of the labeling region until the start of acquisition. The second time is also a time for a liquid present in the labeling region to reach a desired position in the imaging region. The first time is also a time for longitudinal magnetization components of a background tissue to become substantially zero.
