The two versions were designed for different trade-offs between adiabaticity and echo time.
Contrast-to-noise ratio was calculated based on the selected echo time.
This function assumes that all volume were collected using the same echo time.
The principle is illustrated for one- and two-dimensional MRS, in particular the 2D separation experiment, where the usual restriction to equidistant echo time spacings and equal acquisition times per echo time can be abolished.
