Multi-Interleaved X-prepared tse with inTUitive Relaxometry (MIXTURE) is a 3D TSE sequence that can produce high-resolution morphology images and T2 map simultaneously. The purpose of this study was to evaluate MIXTURE FLAIR for T2 measurement of the cranial nerves. MIXTURE FLAIR produced reliable T2 values in the fantom study. The variance of T2 value measured by MIXTURE FLAIR was relatively small, and the T2 value was significantly smaller than multi-echo TSE and MIXTURE T2 in the volunteer study. MIXTURE FLAIR enabled the T2 value measurement of the cranial nerves, which was not previously feasible.
