 Abstract: Balanced SSFP is very sensitive to spin dephasing induced be different mechanisms within the completely balanced gradient scheme. A source of imperfections are eddy currents that change from excitation to excitation produced by the changing phase encode (PE) gradients. Rapid and large changes of the encoded k-space position as seen in conventional 3D PE trajectories generate signal instabilities and fluctuations that lead to image artifacts. Optimized PE trajectories are proposed with minimal changes of k-space position from excitation to excitation.
