ABSTRACT:
In order to provide a magnetic resonance imaging method and apparatus which avoids artifacts due to the motion of a subject when the imaging is conducted with the interval between time phases reduced, a two-dimensional Fourier space is divided into a plurality of regions A,A'-D,D' symmetrically with respect to the frequency axis kx, and data acquisitions for the peripheral regions B and B', C and C', and D and D' are sequentially conducted with the data acquisition for the central regions A and A' interposed each time. At this time, the data acquisition is conducted alternately for each TR in a pair of symmetric regions, thereby minimizing the time difference between symmetric data.
