Robust olefinic fat suppression is of great importance in diffusion tensor imaging (DTI) of skeletal muscle. Current methods may be susceptible to main field inhomogeneities or reduce image quality. We propose a novel use of combined 6- and 2- point Dixon techniques with shortened echo time to eliminate olefinic fat signal in skeletal muscle and demonstrate the feasibility of the new method in healthy volunteers.
