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.
