The spinal cord MRI community currently lacks a standard reference template covering the entire cord, therefore hindering the feasibility of large multi-center studies. Here, we propose the MNI-Poly-AMU50, the first MRI template of the entire spinal cord and brainstem, based on 50 subjects, available for multiple contrasts (T1-, T2- and T2*-weighted), and integrating probabilistic atlases of the white and gray matter. These templates provide a common framework for co-registering multi-parametric data. All developments are freely available as part of the Spinal Cord Toolbox.
