The present invention relates to a method and apparatus for phase distribution and phase correction, and a method and apparatus for magnetic resonance imaging. To calculate a precise phase map even when there is a local phase disturbance and perform this phase correction, an image acquired by magnetic resonance imaging is subjected to low pass filtering (702), pixel positions (704) for which the ratio of a value after filtering to a value before filtering does not exceed a predetermined ratio are detected, a phase distribution excluding pixel data at these positions is calculated, and the phases at the excluded pixel positions are estimated from the phases of neighboring pixel positions to provide compensation so as to complete a phase map.
