What is Radial alternating TE sequence for faster fat suppression about?

## Abstract This study describes a steady‐state sequence that uses a radial __k__‐space trajectory and alternating echo times (TEs) between even and odd __k__‐space views. The sequence generated a single data set that was used to reconstruct images with inherent fat suppression. This fat suppression results from the fat phase variation in alternate echoes giving rise to cancellation in the central portion of __k__‐space. This new fat‐suppression method provides inherent fat suppression in half the acquisition time relative to the radial two‐point Dixon method. The improvement in __k__‐space sampling efficiency is demonstrated in phantom and clinical images, and through measured point‐spread functions (PSFs). As a result, the radial alternating TE sequence offers improved temporal resolution over a radial version of the two‐point Dixon sequence by requiring fewer total projections to obtain the same effective resolution in water‐based tissues.
