Fat suppression is very important for both high contrast morphological imaging and accurate quantitative MR imaging. However, the conventional fat suppression methods such as chemical shift-based fat saturation are not well-suited for short T2 imaging due to the large direct saturation of short T2 tissues with broad spectra. The purpose of this study was to design a novel fat suppression pulse for ultrashort echo time (UTE) imaging of short T2 tissues with well-preserved short T2 signals using a soft-hard composite pulse.
