Quantitative MRI techniques have been shown to be sensitive to changes in diseased spinal cord via measurements of relaxation times, the Magnetisation Transfer Ratio (MTR), and more recently quantitative Magnetisation Transfer (MT) parameters. We have developed an imaging protocol to enable mapping of proton density (PD), T1, MTR, MT and R2* in under 20 minutes. Here we present data acquired in the spinal cords of 12 healthy volunteers using this rapid multi-parameter mapping protocol. This technique may provide an insight into pathological processes occurring in the cervical cord affected by neurological disorders such as Multiple Sclerosis (MS).
