The clinical applicability of magnetic resonance current density imaging (MRCDI) is highly dependent on the sensitivity of the acquired current-induced magnetic flux density ($$$\widetilde{B}_z$$$) distribution. Here, the combined effect of relevant parameters of the ICNE-SPGE pulse sequence on the SNR level and the total acquisition time of the $$$\widetilde{B}_z$$$ images are analyzed. The optimized sequence parameters are estimated to acquire $$$\widetilde{B}_z$$$ images with the highest possible SNR for a given acquisition time or the desired SNR in the shortest scan time. Besides, alternative sequence parameters are estimated to acquire the same SNR level for a given acquisition time.
