| 目的 探讨女性颈椎骨密度与腰椎骨密度的差异及相关性。方法 对46名女性志愿者于同一天行颈椎及腰椎定量CT(QCT)扫描,记录各椎体骨密度数据。分别应用配对样本t检验及Pearson相关分析比较颈椎与腰椎平均骨密度的差异及相关性;采用方差分析比较各椎体骨密度均数,采用LSD法进行组间的两两比较。结果 颈椎平均骨密度为(281.81±76.13)mg/cm3,腰椎为(147.49±39.65)mg/cm3,二者差异有统计学意义(t=19.462,P<0.001)。颈椎与腰椎平均骨密度的相关性高(r=0.86,P<0.001)。结论 女性颈椎平均骨密度高于腰椎,并与腰椎平均骨密度相关性高。 |

| Objective To investigate the difference and correlation of bone mineral density (BMD) with quantitative computed tomography (QCT) between cervical vertebrae and lumbar spine. Methods Forty-six adult female volunteers underwent QCT scanning of cervical and lumbar vertebrae. The difference of mean BMD between cervical vertebrae and lumber vertebrae was statistically analyzed using paired t-test, and then Pearson correlation analysis was used to determine the relationship. Results Mean BMD was (281.81±76.13)mg/cm3 in cervical vertebrae and (147.49±39.65)mg/cm3 in lumbar vertebrae, and the difference was statistically significant (t=19.462, P<0.001). The correlation coefficient of average BMD in cervical and lumbar vertebrae was 0.86 (P<0.001). Conclusion Average BMD of cervical vertebrae is higher than that of lumbar spines in female. The BMD in cervical vertebrae has a high correlation with the BMD in lumbar spine. |
