摘要：

RESULTS AND CONCLUSION:(1) The values of narrow lumbar spinal canal measured by three-dimensional reconstruction CT and MRI were (136.) mm2and (139.) mm2; there were significant differences between them (t=-3.96, P < 0.001). Pearson correlation analysis showed that there was a positive correlation between three-dimensional reconstruction CT and MRI measurement of narrow lumbar spinal canal area (r=0.950, P < 0.001). (2) The values of interobserver ICC and intraobserver ICC were and . The values of interobserver ICC and intraobserver ICC measured by lumbar MRI were higher than those measured by three-dimensional reconstruction CT (P < 0.05). (3) Bland-Altman plot showed that the 95% distribution range of the difference of spinal canal area between the two methods was -8.0-5.5 mm2. Six points were outside the range, accounting for 3.66%. (4) The results showed that there was a significant difference in spinal canal area between three-dimensional reconstruction CT and MRI, but there was a strong positive correlation. The consistency and reproducibility of measurement of narrow lumber spinal canal area by two imaging examinations were good, but the consistency and repeatability of lumbar MRI in measuring narrow lumber spinal canal area were better than that of three-dimensional reconstruction CT.
