Synopsis

Keywords: Neuro: Spinal Cord

The primary focus is on the role of MR imaging with conventional and functional sequences for evaluating spinal cord and nerve root injuries during the acute or chronic phase of injury, with emphasis on specific imaging features and injury classification systems that may aid in diagnosing injury severity and predicting clinical outcome. More recent advances in diffusion imaging including DTI, 3D isotropic heavily T2WI with post-processing images, MR neurography for spinal cord or nerve root evaluation in trauma also are reviewed.

MR imaging assessment of traumatic spinal cord and nerve root injury.
1. epidemiology & pathophysiology
2. conventional MR imaging for spinal cord and nerve root injury
- standard protocol; sagittal T1WI, T2WI, STIR / axial T2 or T2*WI
- additional protocol; fluid-sensitive sequences, gradient -recalled echo T2*, SWI
3. advanced MR sequences
- diffusion weighted image (DWI) including diffusion tensor image (DTI)
- MR neurography
- motion-insensitive imaging technique with deep learning reconstruction
4. Spectrum and imaging findings of traumatic spinal cord and nerve root injury
- cord edema, cord contusion, intramedullary hemorrhage, nerve transection
- root avulsion; pseudomeningocele
- spinal cord injury without radiologic abnormality
