The aim of this work was to develop an optimized sLASER sequence which is capable of acquiring artefact-free data with an echo time as short as 20.1 ms on a whole-body clinical 3 T MR system. This was achieved through the use of specialized pulses and optimizing the crusher scheme and phase cycling schemes. High quality spectra were obtained and quantified in 6 healthy volunteers, both in the prefrontal and the occipital cortex.
