摘要:
 目的：观察并比较定量CT与双能X线骨密度仪测量腰椎各椎体间骨密度的准确性。 方法：100例研究对象选自健康体检者，将其按照不同测量方式分为观察组和对照组。观察组采取双能X线方式，对照组采取定量CT方式，测量腰椎体的骨密度，观察两种方式的测量准确性。 结果：对照组男性和女性的L2-L4椎体骨密度不尽相同，椎体间骨密度值存在明显差异（P<0.05），且由L2-L4以递增趋势呈现。观察组男性和女性的L2-L4椎体骨密度数值无显著差异（P>0.05）。 结论：对腰椎各椎体间骨密度采用定量CT进行测量，可有效提升测量准确度，为临床诊断和治疗疾病提供有效参考。
Abstract:
 Abstract: Objective To compare the accuracy of quantitative computed tomography (CT) and double-energy X-ray bone densitometer for measuring the bone mineral density (BMD) between lumbar vertebrae. Methods A total of 100 healthy subjects were selected and divided into observation group and control group according to different measurement methods. Double-energy X ray was adopted in observation group, while quantitative CT was applied in control group. The accuracies of measurements were analyzed and compared. Results The BMD of L2-L4 vertebral body in males and females from control group was different. Moreover, the differences in BMD between the vertebral body were significant (P<0.05), and the BMD was gradually increased by L2-L4. No statistical differences were found in the BMD of L2-L4 vertebral body in males and females from observation group (P>0.05). Conclusion Using quantitative CT for the measurement of BMD between lumbar vertebrae can effectively improve the accuracy of measurement and provide references for clinical diagnosis and treatment of diseases.
