For T1ρ quantification, a three-dimensional (3D) acquisition is desired to obtain high-resolution images. In this study, we introduced a new sequence, termed MIXTURE (Multi-Interleaved X-prepared TSE with inTUitive RElaxometry), based on 3D magnetization-prepared multi-interleaved TSE, to achieve rapid and robust acquisition of 3D T1ρ mapping data. MIXTURE might be useful for improving the quality and efficiency of 3D T1ρ-mapping.
