An
ultrashort TE (UTE) imaging technique has been developed for the
visualization of tissues with short T2 or T2*, such as menisci and tendons.
UTE methods typically utilize fat suppression to improve the contrast for
tissues with short T2. However, conventional fat-saturation methods achieve
limited success due to the broad short T2* water-peak and the complexity of
the fat spectrum. In this work, we have combined a 2D multi-slice multi-echo
UTE sequence with a water/fat separation technique (IDEAL), to obtain high
contrast short T2 images without the use of any preparation pulse and within
acceptable scan times.
