PROBLEM TO BE SOLVED: To enhance efficiency of diagnostic imaging by warranting the reliable imaging of a magnetic resonance image where an artifact due to the motion of a subject is suppressed. SOLUTION: When determined that a body-motion is produced before starting a main-imaging, a sequence-switching control-unit 17b controls operation so as to switch from a usual-imaging sequence to a body-motion adaptive-sequence corresponding to an imaging-portion of a subject P by referring to a body-motion adaptive-sequence storage-unit 14a. Moreover, upon a determination that a body-motion is produced during the main-imaging according to the usual-imaging sequence, the sequence-switching control-unit 17b controls operation so as to perform a retake by switching to the body-motion adaptive-sequence if an already-collected data-volume is less than a predetermined volume. By contrast, if the already-collected data-volume is equal to or more than the predetermined volume at a time point when determined that a body-motion is produced during the main-imaging according to the usual-imaging sequence, the sequence-switching control-unit 17b stops the main-imaging, and controls a data-processing unit 13 so as to reconstruct a magnetic resonance image only with collected data.
