A blood flow dynamic analysis apparatus for determining 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 with the contrast agent injected therein, includes a time detection unit for detecting a time of data minimal in 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 for fetching a second data sequence which appears prior to the time detected by the time detection unit, from within the first data sequence, a data detection unit for detecting 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 for extracting data from the third data sequence, based on the centrally-located data, and a baseline determination unit for determining the baseline, based on the data extracted by the data extraction unit. |
