Table 2 Temporal evolvement of DTI metrics after spinal cord decompression

From: The role of diffusion tensor imaging as an objective tool for the assessment of motor function recovery after paraplegia in a naturally-occurring large animal model of spinal cord injury

Diffusion metrics SC segment At presentation (n = 17) Follow-up (n = 16) p value
FA; median ± SD Cranial 0.725 (± 0.105) 0.627 (± 0.075) 0.0025
Epicentres 0.781 (± 0.053) 0.611 (± 0.092) < 0.0001
Caudal 0.678 (± 0.087) 0.604 (± 0.074) 0.0049
ADC (10−3mm2/s); median ± SD Cranial 0.999 (± 0.317) 1.224 (± 0.575) 0.0156
Epicentres 0.817 (± 0.236) 1.134 (± 0.366) 0.0016
Caudal 0.985 (± 0.197) 1.198 (± 0.507) 0.0646
  1. Italic values indicate significance of p value (p < 0.05)
  2. Epicentres: ROIs placed in spinal cord compressed by herniated nucleus pulposus material, directly above the respective intervertebral disc space. Cranially: ROIs placed in spinal cord one vertebral body cranially to epicentres. Caudally: ROIs placed in spinal cord one vertebral body caudal to epicentres
