However, in order to make tissue-specific quantitative measurements within the cord a robust co-registration is required. We investigated various linear registration methods within the FSL software package for co-registration of multi-modal cervical cord MRI data and the optimum method was used to register multi-modal spinal cord data, thus allowing the estimation of multi-parameter map values in white and grey matter regions within the cord.
