Purpose
J‐Difference editing (MEGA) provides an effective spectroscopic means of selectively measuring low‐concentration metabolites having weakly coupled spins. The fractional inphase and antiphase coherences are determined by the radiofrequency (RF) pulses and inter‐RF pulse intervals of the sequence. We examined the timings of the spectrally selective editing 180° pulses (E180) in MEGA‐PRESS to...
