1. A blood flow dynamic analysis apparatus configured to determine a baseline indicative of a signal strength prior to an arrival of a contrast agent to a predetermined region of a subject, based on MR signals collected in time series from the predetermined region of the subject said blood flow dynamic analysis apparatus comprising:

  • a time detection unit configured to detect a time of data having a minimal signal strength, of a first data sequence in which data of signal strengths of the MR signals are arranged in time series;

    a data fetch unit configured to fetch a second data sequence which appears prior to the time detected by said time detection unit, from within the first data sequence;

    a data detection unit configured to detect centrally-located data from within a third data sequence obtained by sorting the second data sequence in the order of magnitudes of the signals strengths;

    a data extraction unit configured to extract data from the third data sequence, based on the centrally-located data; and

    a baseline determination unit configured to determine the baseline, based on the data extracted by said data extraction unit.
