The presented research details the differences between slice localized and volume localized EP-COSI data sets. Slice localization enables shorter echo times and thus signal acquisition with less T2 losses. The result is increased SNR in the resulting EP-COSI data set. The drawback is more leakage from outer volume signal. When outer volume suppression is achievable more SNR is achievable using slice localization, when it is not the ideal localization scheme is volume based. Both sequences are capable of differentiating J-coupled off diagonal resonances.
