Accelerated single UTE-Dixon for simultaneous short T2*water and fat imaging using a FLORET trajectory

Ultra-short echo time (UTE) imaging enables the depiction of short-T2* tissues and is being increasingly used for the generation of CT-like bone images. UTE imaging has been recently combined with single-echo Dixon processing to enable the separation of water and fat signals from a single echo UTE image, but was primarily previously employed in radial stack-of-stars UTE acquisitions with prolonged scan durations. The present work combines single UTE-Dixon processing with a Fermat looped, orthogonally encoded trajectory (FLORET) to enable accelerated simultaneous short T2* water- and fat-separated imaging at sub-millimeter isotropic resolution. The technique is applied in the ankle.
