The presented research details the differences between slice localized and volume localized EPSI data sets. Slice localization enables shorter echo times and thus signal acquisition with less T2 losses. The results show increased SNR in the acquired EPSI data set. The drawback is more leakage or contamination from outer volume signal, namely skull marrow lipids in brain. When outer volume suppression is achievable more SNR can be obtained using slice localization compared to volume localization.
