A magnetic resonance imaging method for achieving water-fat separation; the method includes utilizing BLADE trajectories to collect the original data of one in-phase image and the original data of two out-of-phase images; reconstructing the in-phase image on the basis of the original data of the in-phase image, and utilizing the original data of the in-phase image to perform phase correction on the original data of the out-of-phase images, and reconstructing the out-of-phase images; and calculating the images of water and fat on the basis of the in-phase image and the out-of-phase images. Since the BLADE trajectory is used to acquire the k-space data, it provides the advantages that the BLADE trajectories are insensitive to the motion and pulsation of a rigid body, reduce the degree of sensitivity to motion artifacts, and also improve the images' signal-to-noise ratio.
