Applying simultaneous-multi-slice EPI (SMS EPI) sequences in diffusion-weighted imaging (DWI) can reduce scanning time greatly, but its clinical-routine image quality in different body parts has not been broadly tested. This study compared multi-site DWI images acquired with a prototype SMS EPI sequence with those acquired with a traditional EPI sequence, computed SNR and CNR and conducted paired t-test. The results show there are no significant differences of SNR and CNR between the two kinds of sequence (p>0.05). When the SMS EPI sequence was applied to the clinical DWI examination, it not only reduced scanning time, but also kept the SNR, CNR in the same level as standard EPI. The SMS sequence was able to satisfy the requirements of clinical disease diagnosis.
