Due to the difficulty in distinguishing the structure of spinal by conventional MR sequence. In this study, the fusion images of Phase Sensitive Inversion Recovery sequence (PSIR) and zoomed Diffusion Tensor Imaging (DTI) was used to quantify the diffusion indicators, such as fractional anisotropy (FA), apparent diffusion coefficient (ADC), axial dispersion (AD) and relative anisotropy (RA) in the normal spinal cord. We found that there were significant differences of above indicators in different regions of cervical cord including the white columns of the cervical cord, the ipsilateral white matter and in the left and right sides of the cervical cord.
