Diffusion tensor imaging (DTI) and tractography are useful for predicting outcomes after traumatic cervical spinal cord injury (SCI). Preoperative imaging offers better results and lower failure rates than postoperative imaging for SCI prognosis.

Area of Science:

  • Neuroimaging
  • Spinal Cord Injury Research

Background:

  • Traumatic cervical spinal cord injury (SCI) significantly impacts neurological and functional status.
  • Predicting outcomes in SCI patients is crucial for effective treatment planning.

Purpose of the Study:

  • To evaluate the clinical utility of diffusion tensor imaging (DTI) and tractography in predicting outcomes after traumatic cervical SCI.
  • To compare the predictive accuracy of DTI and tractography performed before versus after surgery.

Main Methods:

  • Sixty-one patients with traumatic cervical SCI were randomized into pre-operative or post-operative DTI groups.
  • Fractional anisotropy (FA), apparent diffusion coefficient (ADC) values, and tractography metrics (fiber numbers) were analyzed.
  • Neurological and functional statuses were assessed at 4 and 8 weeks post-injury.

Main Results:

  • Preoperative DTI showed higher FA and lower ADC values with a significantly lower image analysis failure rate compared to postoperative DTI.
  • Postoperative DTI data correlated significantly with the patient's clinical status at evaluation.
  • Specific DTI and tractography parameters correlated with neurological and functional outcomes, especially when DTI was combined with physical examination.

Conclusions:

  • Preoperative DTI and tractography are valuable for predicting outcomes in traumatic cervical SCI due to better image quality and lower failure rates.
  • Postoperative DTI and tractography reflect the current clinical state but are less predictive of long-term outcomes compared to preoperative assessments.
  • DTI and tractography should be interpreted separately based on their timing (preoperative vs. postoperative) relative to spine surgery for SCI.
