ABSTRACT:
In a method for identifying spikes in magnetic resonance signals obtained in magnetic resonance tomography, a magnetic resonance signal is obtained and is high-pass filtered. A statistical evaluation of the high-pass filtered magnetic resonance signal is then undertaken to determine whether the high-pass filtered magnetic resonance signal contains spikes which can be differentiated from a noise signal. If so, such spikes are identified, and can be removed from the raw data so that they do not contribute to image artifacts.
