A simple method for cusp artifact removal by gradient optimization

In this abstract, we proposed an easy-to-implement method to eliminate cusp artifacts, or called annefact, by optimizing the pulse sequence design in FSE. The gradient polarities for excitation and refocusing RF slice selection are the same. However, the amplitudes of excitation and refocusing gradients are optimized individually so that location shift of excited spins by the two RF is minimized, whereas the annefact regions correspond to the two RF are separated. The former ensures no signal drop takes place. The latter ensures no cusp artifact is formed. This method requires no additional post-processing and hardware modification.
