Detailed Description
Injury of the spinal cord, for instance induced by trauma, is complex involving primary mechanisms caused by forces directly affecting the spinal cord and secondary mechanisms consisting of complex physiological processes after trauma.
Conventional magnetic resonance imaging (MRI) is the current standard to assess morphologic changes of the spinal cord after injury. However, conventional MRI provides little information regarding the health and integrity of the brain and spinal cord tissue itself, due to the fact that signal intensity changes are non-specific and do not correspond directly with physiological processes. This is reflected in the poor correlation of conventional MRI data with neurological and functional impairment in various spinal cord pathologies (such as multiple sclerosis compression myelopathy) and failure to provide reliable prognostic information.
By applying a combination of diffusion weighted imaging, functional MRI and magnetic resonance spectroscopy will give us a better understanding of the changes after injury of the cervical spinal cord, brainstem and brain. Correlating the imaging data with the neurological and clinical status of patients could improve the patient status prediction and therapy planning.
This study is divided into three sub-projects:
i) Reproducibility study of the MR measurements in healthy controls ii) Progression of MR biomarkers in subacute patients with SCI and comparison to chronic patients with SCI iii) Prediction of clinical outcome based on MR biomarkers

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Fractional Anisotropy (FA)
Time Frame: 16-40 days after injury, 70-96 days after injury, 150- 186 days after injury
|
Degree of anisotropy of a diffusion process (value between zero and one).
A value of zero means that diffusion is isotropic, i.e. it is unrestricted (or equally restricted) in all directions.
A value of one means that diffusion occurs only along one axis and is fully restricted along all other directions.
FA is a measure often used in diffusion imaging where it is thought to reflect fiber density, axonal diameter, and myelination in white matter.

Time Frame: 16-40 days after injury, 70-96 days after injury, 150- 186 days after injury
|
Measurement of the magnitude of diffusion (of water molecules) within tissue
|

|
Change in Relative Anisotropy (RA)
Time Frame: 16-40 days after injury, 70-96 days after injury, 150- 186 days after injury
|
