The present invention provides a phase cycling method capable of obtaining images based on the phase cycling method in the same time as when no phase cycling method is used, and a magnetic resonance imaging apparatus therefor. In the phase cycling method, the amount of increment/decrement in the phase of each .alpha..degree. pulse (i.e., RF transmission phase) is changed upon data acquisition in a positive low frequency domain on a k space and upon data acquisition in a negative low frequency domain to carry out phase cycling. The amount of increment/decrement in the RF transmission phase changes so as to differ at the start of data acquisition and the end of data acquisition. The amount of its change varies between 0 and a predetermined value. The predetermined value is set to such a degree that the amount of increment/decrement in the RF transmission phase is gradually changed, in such a manner that a steady state can be maintained on a pseudo basis. A method for determining the predetermined value is not limited by or to the present invention. For example, values obtained empirically can be used.
