Aim:We aimed to evaluate the normal values of cervical spinal canal diameter and spinal cord diameter-area by magnetic resonance imaging (MRI) in adult Turkish population, in this study. It was investigated whether the values changed according to age, gender and spinal cord levels. Material and Method:We retrospectively examined cervical MRI of 300 adult patients (150 female / 150 male). The patients were divided into 3 groups (18-39, 40-59 and over 60 years old) according to their age. Spinal canal and spinal cord diameter were measured in the sagittal plane and the spinal cord area in the axial plane from the C3 and C6 levels.Results: Gender affects the normal values of the cervical spinal canal and spinal cord diameter. Both spinal cord and spinal canal measurements were found to be higher in men than in women. Spinal cord diameter and area were found to be lower at the C6 level than at the C3 level, regardless of gender. Both spinal canal diameter and spinal cord area decreased from cranial to caudal (C3-C6). Significant differences were detected in our data in the evaluation of age-related groups, and age was found to be effective in determining the normal parameter. Conclusion:In conclusion, cervical spinal canal and spinal cord measurements in healthy individuals vary depending on age, gender and cord level.
