MAGNETIC RESONANCE IMAGING WITH IMPROVED IMAGING CONTRAST

摘要

A method of magnetic resonance imaging of an object comprises the steps of arranging the object in a stationary magnetic field, subjecting the object to an excitation and encoding sequence of magnetic field gradients resulting in k-space sampling in two segments along the phase encoding direction, wherein the encoding sequence of the magnetic field gradients is selected such that the two segments in k-space are sampled along trajectories beginning with a central k-space line through the k-space center and continuing to opposite k-space borders of the two segments, collecting magnetic resonance signals created in the object, and reconstructing an image of the object based on the magnetic resonance signals, wherein one central k-space line is sampled in both of the two k-space segments, and intersegment phase and/or intensity deviations are corrected in both k-space segments using the magnetic resonance signals collected along the central k-space line. Furthermore, an imaging device for magnetic resonance imaging of an object is described.
