Diffusion tensor imaging (DTI) has a severe problem such as high geometric distortion and body motion. To solve these problems, we attempted to apply a split acquisition of fast spin-echo signals for diffusion imaging (SPLICE) instead of conventional Mx-eliminated TSE-DTI. In addition, so as to improve the incoherent signal phase due to motion, SPLICE was combined with MultiVane (known as PROPELLER) which is to sample k-space in a rotating fashion using a set of radially directed blades. In this study, we evaluated the effect of accuracy and reproducibility of the quantitative values in lumbar nerve roots using MultiVane-SPLICE-DTI.
