In vivo cervical spinal cord measurements using computed tomography are 15-20% smaller than traditional autopsy data. This study provides updated in vivo dimensions for the cervical spinal cord.

Area of Science:

  • Neurosurgery
  • Radiology
  • Anatomy

Background:

  • Autopsy data traditionally define cervical spinal cord dimensions.
  • Real-time radiographic studies have questioned the accuracy of autopsy-based measurements.

Purpose of the Study:

  • To measure cervical spinal cord dimensions in vivo.
  • To compare in vivo findings with existing literature, particularly autopsy data.

Main Methods:

  • Retrospective analysis of 102 patients with cervical radiculopathy symptoms.
  • Measurement of anteroposterior and transverse diameters, anterior median fissure depth, and cross-sectional area from C2 to T1 using postmyelogram computed tomography.
  • Comparison of measurements with autopsy data.

Main Results:

  • No significant differences in measurements based on age or sex.
  • Cervical spinal cord dimensions measured via computed tomography were 15-20% smaller than autopsy-derived values.
  • Maximum transverse diameter and cross-sectional area were observed at C5.

Conclusions:

  • In vivo computed tomography measurements of the cervical spinal cord are smaller than those reported from autopsy data.
  • Updated in vivo measurements are crucial for accurate clinical assessment and surgical planning.
