Objective:
To utilize Spinal Cord Toolbox (SCT) to measure the morphological parameters of healthy cervical spinal cords and explore the impact of gender, age and vertebral levels on them.
Methods:
A retrospective study was conducted, collecting cervical spinal cord magnetic resonance images of 184 healthy adults. Then, cross-sectional area (CSA), eccentricity, antero-posterior diameter (AP) and right-left diameter (RL) were each computed for every subject. Then, impacts of gender, age and vertebral level on CSA and eccentricity were explored. Moreover, linear correlation analysis was conducted among CSA, AP and RL.
Results:
The CSA of the cervical spinal cord in males was significantly larger than that in females at C2~C7 segments (P＜0.05) . For C2~C6 segments, there was no statistically significant difference in CSA between the young and middle-aged groups, but both were significantly larger than that of the elderly group. CSA of C4 was the largest whereas CSA of C7 was the smallest. Eccentricity values of C4 and C5 were significantly larger than those of other vertebral levels (P＜0.05). Linear correlation was established between CSA, AP and RL at C2~C7 segments.
Conclusion:
The results allow for minimizing inter-subject variability using normalization, and thereby highlighting the importance of morphological parameters as biomarkers in the research of cervical spinal lesions.
