Role of MRI in evaluation of Compressive myelopathy
Journal Title: Indian Journal of Neurosciences - Year 2017, Vol 3, Issue 2
Abstract
• Compressive Myelopathy is the term used to describe the spinal cord compression either from outside or within the cord itself. • Spinal cord injury is the major cause of quadriplegia and disability. • Plain radiographs have a low sensitivity for identifying traumatic spinal lesions. Therefore trauma victims with plain films negative for spine injury but with a high clinical suspicion of injury should undergo MR for a more definitive evaluation of the spine. • MRI is the definitive modality in assessing spinal soft tissue injuries, especially in evaluation of spinal cord, intervertebral discs and ligaments. • In case of spinal trauma, MRI demonstrates the relationship of fractured / subluxated vertebral bodies to the cord and highlights a significant stenosis. The signal abnormalities within this cord can be identified, helping to localize and define the degree of trauma. • In case of suspected cord compression due to neoplasm MRI serves as an excellent method for imaging tumor involving spinal column, canal and cord. • Many spinal cord diseases are reversible if recognized and treated at an early stage; thus they are amongst the most critical of all Neurologic emergencies. • The role of MRI is to distinguish compressive from non-compressive myelopathy. Once compressive lesions have been excluded, non-compressive cause of acute Myelopathy that are intrinsic to the cord are considered primarily vascular, inflammatory and infectious etiologies.
