MR images are reconstructed from K space raw data. Sometimes K space raw data can be corrupted with high amplitude value noise, resulting gross striation artifact. This noise is referred as spike noise. The causes of these spikes can be arcing, loose connection or other electrical/mechanical problems in system. Spike noise is difficult to diagnosis and usually it is cost and time consuming job to fix a spike noise issue.
