In this study, we have developed a multi-echo UTE-DESS
pulse sequence. UTE-DESS offers rapid and
high-resolution imaging of short T2 tissues with
proton-density, T2, and diffusion contrasts, along with
fat-water separation and a very high overall scan
efficiency. We present our initial results of scanning
the knees of healthy volunteers with multi-echo
UTE-DESS. Our preliminary data shows that the contrasts
generated by this sequence and its ability for fast
imaging, makes the sequence potentially attractive for
routine clinical study of the morphology of the
connective tissues in the knee.
