The educational objectives of this article are to describe the technical challenges and recent developed methods of DWI and DTI in spinal cord imaging

1. To illustrate of technical challenging of DWI in spinal cord and vertebrae;  sensitivity to magnetic field inhomogeneity, small diameter of spinal cord and lesion, lack of discernible pattern, partial volume averaging, bulk physiologic motion about the spinal cord 2. To illustrate technical consideration: proper image acquisition without distortion, high SNR, available scanning time, proper b-value, orientation of diffusion encoding directions, etc. 3. To describe advanced EPI based technique to overcome geometric distortion; multishot EPI, parallel imaging, reduced FOV method.
