1. A method for Magnetic Resonance Imaging to depict a 3 -dimensional object by an image having pixels representing volume elements of the object, comprising: immobilising the object and acquiring a reference image of the object with a receiver coil at a first echo time immediately following an excitation by a transmitter coil, wherein said reference image is complex-valued, representing each volume element by a pixel with a reference magnitude value and a reference phase value; keeping the object immobilised and acquiring a target image of the object with said receiver coil at a pre-selected second echo time, significantly longer than said first echo time, following the same or another excitation by said transmitter coil, wherein said target image is complex-valued, representing each volume element by a pixel with a target magnitude value and a target phase value; subtracting, pixel by pixel, the reference phase value from the target phase value to obtain a corrected phase value for each pixel; and obtaining said image from said target magnitude values and said corrected phase values.
