To find clinically feasible combinations of parameter for simultaneous multi-slice echo planar imaging (SMS-EPI) acquisition diffusion tensor imaging (DTI), we investigated the combinations of SMS factors and the amounts of inter-slice image shift to find which one can provide better signal-to-noise ratio (SNR) by two different head coils (20ch and 32ch), respectively. The SMS factors 2 and 3 with imaging shifts (>1/2) on 32ch judged clinically feasible and can be substituted on conventional DTI. The SMS factor 2 with imaging shifts 0, 1/2, 1/4 on 20ch head coil judged clinically feasible.
