Spectral-Spatial Long-T2 Suppression Pulses for Multislice UTE Imaging

Long-T2 suppression pulses create excellent contrast for short-T2 species imaged with ultra-short echo time (UTE) imaging. Previous pulses have been spatially non-selective, making them unsuitable for interleaved multislice acquisitions. This is because the pulse is applied once per TR, causing T1 recovery to compromise the suppression in later slices. We have designed spectral-spatial long-T2 suppression pulses for multislice UTE imaging that perform as well as previous pulses and can be applied for every slice, eliminating the problems associated with T1 recovery.
