The Viewpoint of Highly Accurate Fractional Anisotropy Value Using 3-Tesla Zoom Diffusion Tensor Imaging in Spinal Spondylotic Disease—Aligned Fibers Effect—

Objective : To assess the perioperative fractional anisotropy (FA) /apparent diffusion coefficient (ADC) change in patients with cerebrospinal disease using highly accurate diffusion tensor imaging (Zoom DTI), and to determine the prognostic value.
