Neuroradiological Imaging: Techniques and Prognostication

Traumatic spinal cord injury (TSCI) represents a significant cause of morbidity and disability, necessitating early and accurate evaluation to optimize clinical outcomes. Neuroradiological imaging techniques play a pivotal role in the diagnosis, classification, and prognostication of TSCI. Advanced imaging modalities, including computed tomography (CT), magnetic resonance imaging (MRI), and emerging techniques like diffusion tensor imaging (DTI), provide detailed assessments of structural and functional damage. CT offers rapid evaluation of osseous injuries and spinal alignment, while MRI excels in the visualization of soft tissue structures, including spinal cord edema, haemorrhage, and ligamentous disruption. MRI-based biomarkers, such as the extent of cord compression, haemorrhage, and diffusion abnormalities, have shown strong correlations with neurological outcomes. Quantitative imaging metrics, like fractional anisotropy from DTI, offer insights into microstructural integrity and potential recovery. Neuroradiological imaging not only provides critical information for acute management strategies but also aids in monitoring recovery and guiding rehabilitation. Indeed, prognostication relies on integrating imaging findings with clinical parameters, such as the American Spinal Injury Association (ASIA) impairment scale. Continued research and technological advancements are essential to refine imaging-based prognostic models, ultimately improving the quality of care for TSCI patients.
