In musculoskeletal imaging there is an abundance of water and fat interfaces leading to problems of image blurring. These interfaces are particularly programmatic when acquiring images with very short TE in order to visualize rapidly decaying signals such as cortical bone, tendons etc. Such an imaging acquisition approach is recently introduced, novel acquisition scheme SWIFT (Sweep Imaging with Fourier Transform) which operates with an effective TE~0. Here we introduce for the first time a water/fat saturation scheme in SWIFT and demonstrate that selectively saturated SWIFT images display resolved bone ultrastructure including lamellar organization of bone, tendon- cortical bone interface and trabeculae.
