The acceptance of 3D TSE sequences in spine imaging has been low up to now, mainly because of their long scan times. In this work, their acceleration by a combination of compressed sensing and parallel imaging was investigated. Moreover, their extension by an integration of chemical shift encoding was explored to obtain two contrasts simultaneously. For this purpose, a 3D dual-echo Dixon TSE sequence was implemented and evaluated in T₂-weighted imaging of the lumbar spine.
