Gradient‐Enhanced Band‐Filtering Experiments

This paper is devoted to sequences involving a selective inverting pulse bracketed by two identicalB0 gradient pulses [pulse field gradient spin echo (PFGSE)]. The merits of a single PFGSE experimentvs. a double PFGSE experiments are discussed. It is shown that the SPFGSE experiment gives results comparable to the DFGSE experiment provided that the selective inverting profile is sufficiently clean. Extension of this type of experiment withB1 gradients is considered.
