The use of advanced MRI modalities to study brain disease has provided new insights into the understanding of the pathophysiologic mechanisms of several neurologic disorders. It is notable that many of these modalities have not been widely applied to the spinal cord (SC), mainly because of the technical hurdles in performing high-confidence MRI acquisitions in this long, yet thin structure located deep to other structures with high magnetic susceptibility.1 More recently, however, technical developments have improved MRI of the SC. Optimization of specific sequences (e.g., diffusion tensor imaging [DTI]) for SC anatomy,2 higher field strength, and new coil technology have helped conventional and quantitative MRI of the SC to become more sensitive, specific, and accurate.1
