The purpose of this exhibit is to present the feasibility of MR g-ratio mapping for whole brain and cervical spinal cord using a 10 minute protocol. This protocol is appropriate for clinical use and provides reasonable image quality for clinical diagnosis. In vivo MR g-ratio mapping warrants daily clinical use as it has potential to provide additional information about WM microstructure and its changes in pathology.
