Clinical application of UTE (ultrashort echo time) sequences in musculoskeletal studies remains limited, despite their potential to unveil quantitative short-T2* information of e.g. tendons or ligaments. The major shortcoming of quantitative mapping is the considerably longer scan time compared to conventional, anatomical imaging sequences. We investigated the feasibility and use of an isotropic 3D radial compressed sensing UTE (CUTE) prototype sequence for quantitative mapping of short-T2* components in the knee. Similar image quality and T2* values were obtained for non-accelerated and accelerated acquisitions. Thus, CUTE sequences show great promise for fast and clinically feasible UTE T2* mapping.
