 Abstract: RF-spoiled gradient echo sequences are widely used in clinical MRI. However, the theoretical description of the measured signal is not trivial, as a pseudo steady state of the voxel magnetisation is built up. We demonstrate that the well known occasional occurrence of ghost artifacts is a direct consequence of the existence of the PSS, and that there is no rigid rule for the needed moment of the spoiler gradient of an RF spoiled gradient echo sequence.
