Optimization of acquisition parameters of diffusion-tensor magnetic resonance imaging in the spinal cord.

Abstract

Objective: The purpose of this study was to optimize imaging parameters for diffusion tensor imaging (DTI) of the cervical spinal cord using a recently developed sensitivity-encoded (SENSE) imaging technique, which can substantially reduce susceptibility artifacts.Conclusion: Optimal parameters for DTI in the cervical spinal cordincluded a b-value of 900 secondsmm2, 15 diffusion gradient directions, 5 excitations, and a slice thickness of 4mm.
