In the past few years, the signal dependence on the echo time (TE) and mixing time (TM) in the STEAM sequence has been investigated for a number of coupled spin systems, at field strengths of 1.5 3 T. With increasing B0, the spectra of coupled spin systems become more sensitive to small changes in the timing parameters (TE and TM) of STEAM sequences. The aim of the present study was to evaluate the effects of higher B0, (> 3 T) on the AB spin system of citrate and to elucidate the novel coherence behaviour unique to these high B0.
