K-Space Tool: Large Peripheral RF Spike

The RF spike is in the bottom-left quadrant of k-space, half way between the centre and the edge. The periodicity of the artefact is high because the spike is located at a point which represents a higher spatial frequency. Because the RF spike is big, the artefact still obscures a significant amount of contrast. Here it is a typical "corduroy" effect.
