PROBLEM TO BE SOLVED: To satably control blood artifact even if T1 time of bloodstream is shorten by administering contrast medicine to a subject. SOLUTION: A saturation pulse to mitigate MR signal from bloodstream which is flown in a region of interest is applied then the region of interest is excited selectively and a scan for imaging which corrects MR signal, i.e., by exciting the region of interest selectively is carried out. In such a case, a flip angle for the saturation pulse is set as the same degree of the flip angle of the scan of imaging. For example, these flip angles are set to a smaller value than 90 deg. respectively. When the scan for imaging is carried out based on a selective exciting method to the region of interest, a moving direction of the part which is excited selectively is set toward an opposite direction to a flowing direction of bloodstream.
