Using on the open-source pulse sequence programming platform Pulseq, we successfully developed and implemented the gSlider sequence on a 3T scanner without the vendor-specific sequence development environment. One-millimeter whole-brain isotropic dMRI data was acquired using the gSlider implementation from Pulseq and Siemens and test-retest variability was evaluated. The test-retest reliability in fractional anisotropy improved dramatically for the Pulseq implementation while it was comparable for both implementations for mean diffusivity. We demonstrated the feasibility of implementing advanced sequences using the open-source Pulseq platform and expect that it will be easily transferred to and executed on different vendors.
