Abstract



 




The clinical applicability of magnetic resonance current density imaging (MRCDI) is highly dependent on the sensitivity of the acquired current-induced magnetic flux density (




˜

B

z) distribution. Here, the combined effect of relevant parameters of the ICNE-SPGE pulse sequence on the SNR leveland the total acquisition time of the 




˜

B

z images are analyzed. The optimized sequence parameters are estimated to acquire 




˜

B

z images with the highestpossible SNR for a given acquisition time or the desired SNR in the shortest scan time. Besides, alternative sequence parameters are estimated toacquire the same SNR level for a given acquisition time.
