Depending on the intensity and how the sequence changes the magnet field with the radiofrequency pulse we can see that in the same patient the artifacts can occur. a Cine-MR retrospective gating without artifact. b Spectroscopy CMR prospective gating using two R–R intervals with a base line noise correlated to the pulse sequence (white arrow). If the amplitude of the R wave is not sufficient it can lead to a false triggering (not in this case)
