T2 and diffusion measurements are usually acquire in different scans. In this work we propose a multi echo multi shot diffusion sequence that allows us obtaining T2 and mean diffusivity from a single scan. The multi shot approach enable short echo times for both echoes. This characteristic makes this sequence suitable to be applied in tissues with short T2. Result of in vivo experiments show an excellent correlation of T2 and mean diffusivity of the muscle compare to standard scans.
