Abstract:
In a magnetic resonance method and system to create a difference image, essentially only one k-space point in a k-space data set belonging to the difference image is acquired at least twice in the form of k-space measurement values after a radiation of an RF excitation pulse. The difference image is thereby created depending on acquired k-space data set by means of taking the difference of the respective at least two results acquired per k-space point. For each essentially only one k-space point shift multiple phase coding gradients are activated in respective spatial directions, followed by a first readout of the essentially only one k-space point for an acquisition of a first of the k-space measurement values. The phase coding gradients are subsequently modified such that a gradient moment for each of the phase coding gradients is zero for a time period from the first readout of the essentially only one k-space point up to a second readout of the essentially only one k-space point. The essentially only one k-space point is subsequently read out a second time.
