About

In patients with chronic spinal cord injury, imaging of the spinal cord and brain above the level of the lesion provides evidence of neural degeneration; however, the spatial and temporal patterns of progression and their relation to clinical outcomes are uncertain. New interventions targeting acute spinal cord injury have entered clinical trials but neuroimaging outcomes as responsive markers of treatment have yet to be established. We aim to use MRI to assess neuronal degeneration above and below the level of the lesion after acute spinal cord injury. In our prospective longitudinal study, we enroll patients with acute traumatic spinal cord injury and healthy controls. We assess patients clinically and by MRI at baseline, 2 months, 6 months, 12 months, and if possible 24 months and 60 months follow-up, and controls by MRI at the same timepoints. We assess cervical atrophy in white and gray matter and use cross-sectional spinal cord area measurements to assess atrophy at cervical level (C2/C3) and in the lumbar enlargement. We use myelinsensitive magnetisation transfer (MT) and longitudinal relaxation rate (R1) maps in the brain to assess microstructural changes associated with myelin. We also use diffusion tensor imaging acquired in the spinal cord at C2/C3 and in the lumbar enlargement to identify axonal loss and demyelination in the spinal white matter. Finally, we assess associations between MRI parameters and clinical improvement.
