1. A method for producing an image of a subject with a magnetic resonance imaging (MRI) system, the steps comprising a) acquiring a first k-space data set with the MRI system using a first pulse sequence; b) acquiring a second k-space data set with the MRI system using a second pulse sequence which is different from the first pulse sequence; c) reconstructing first and second complex images of the subject from the respective first and second k-space data sets; d) calculating a phase difference image from the first and second complex images; e) calculating a magnitude image from one of said first or second complex images; and f) combining the phase difference image with the magnitude image to form the image of the subject.
