The sequence schemes. A, Traditional EPSI sequence makes use of a slice selective amplitude‐modulated refocusing pulse. B, The proposed new 2π‐CSAP‐EPSI sequence is using a CSAP pair. SLOW spectral‐editing sequence scheme integrated into EPSI is based on the scheme displayed in (A). C, Chemical selectively refocusing the full offset frequency range of the J‐coupled spin system to be edited. C′, Chemical selectively refocusing the partial range of interested spins
