Consistent Signal for Non-CPMG Echo Trains

Diffusion Weighting precludes the use of CPMG echo trains in FSE without crushing significant signal. The MLEV and LeRoux phase cycling schemes help stabilize the signal magnitude, but some residual signal dependence on the starting phase remains. This work illustrates that appropriately placed gradient pulses can remove this residual signal instability.
