Diffusion weighted stimulated echo imaging is often used for diffusion encoding with very high b-values and long diffusion times. For long diffusion times a significant bias can be introduced through the diffusion encoding effect of the slice selection gradients. Compensation of this effect has recently been achieved by adjustment of the prescribed diffusion encoding gradients, but the adjustment is specific to the exact choice of experimental parameters. This report demonstrates that the effect can be minimized through reduction of the diffusion encoding effect of the slice selection gradients themselves, thereby maintaining the fidelity of any applied diffusion encoding scheme.
