Ultrashort echo time (UTE) pulse sequences have the unique ability to visualize short T2 tissues. While several UTE techniques have been implemented and demonstrated good clinical results, there currently does not exist a flexible and robust UTE pulse sequence which can easily manipulate multiple parameters “on-the-fly“ (i.e. selection of trajectories, excitation pulses, acquisition parameters, etc.), and obtain several complimentary scans in a single scan session. In this work we present a newly developed hybrid UTE pulse sequence that includes multiple excitation pulses, and varying trajectories, allowing for novel investigations in studying short T2 tissues.
