We propose a new sequence called MIXTURE (Multi-Interleaved X-prepared TSE with inTUitive RElaxometry). MIXTURE is a 3D TSE that can set arbitrary echo times using the T2 preparation pulses, and enables several image contrasts (such as PDW, T2W) and T2 mapping by acquiring at least two echo time images. In this study, we evaluated the clinical feasibility of morphological and pathological MRI with two contrasts images and quantitative MRI with T2 mapping using MIXTURE.
