A method of MR dynamic imaging comprises the steps of uniformly dividing one scan which is a minimum measurement unit in generating one image data into a plurality of cycles, sequentially extracting one-scan data which are staggered by a predetermined number of cycles, from a series of data derived by repeating the scan a plurality of times in such a manner that the measurement data in each cycle includes high frequency component and low frequency component of the image, and generating image data from the extracted data.
