Use of fat saturation pulses with UTE sequences can improve short T2 contrast and parameter estimation, but can reduce the short T2 signal due to the broad spectrum. Moreover, conventional two-/three-point Dixon-based methods can misestimate fat contents due to the short T2* decay in UTE imaging. In this study, we demonstrate feasibility and efficacy of a single point Dixon method to suppress fat for morphological and quantitative UTE imaging. We evaluate the proposed framework in in vivo experiments in a clinical 3T MR system: morphological UTE imaging and UTE-T1 mapping in knee joints and UTE-bone imaging in a leg.
