Ultrashort echo time (UTE) pulse sequences can capture the signal from short T2 tissues. Many UTE techniques have been developed for achieving an ultrashort TE (less than 0.1 ms) or enhancing the short T2 contrast. However, these approaches have not been extensively compared head-to-head due to the lack of a flexible UTE sequence that integrates the different approaches. Therefore, in this work, we developed a versatile UTE sequence that can directly compare UTE approaches and provide options for researchers to choose the appropriate UTE that fit the particular application.
