Balanced steady-state free precession sequences offer the highest signal-to-noise ratio and encode multiple physical parameters into the signal. However, the sequence is prone to eddy current-induced steady-state disruptions that can severely compromise the image quality or the physical parameter quantification. In this work we describe how the eddy currents act on the signal evolution and propose a novel prospective solution that in principle is applicable to any MRI examination.
