Diffusion-weighted MRS was successfully implemented at short TE, reaching ultra-high b values >20 ms/μm2 on a 3T Siemens Connectom system. With simultaneous fitting for different b-value spectra, macromolecular background patterns are estimated using different approaches to model metabolite diffusion and different macromolecular signal parameterization in gray matter and white matter.
