数字X线骨密度测量技术用于骨质疏松诊断标准的研究

Study of diagnostic standard of osteoporosis using the digital X-ray bone mineral densitometry

目的利用数字X线机骨密度测量系统对南宁地区健康人群进行临床调查,获取南宁地区男女性X线骨密度正常值,并建立初步的临床诊断标准。方法利用数字X线机及XBMS测量软件,采用标准体模,对南宁地区1092例(男性561例,女性531例)健康人群的前臂远端骨密度进行了临床测定,分年龄组统计处理,并找出男女性骨峰值,初步制定了临床诊断标准。结果临床调查表明男女性前臂远端X线骨密度峰值均在30～39岁组[男性(0.867±0.123)g/cm2;女性(0.778±0.072)g/cm2],峰值以后随年龄逐渐降低。结论临床调查证实,数字X线机骨密度测量系统用于临床骨密度检查有较高的精度和准确度,方法简便,易于推广使用。

Objective Clinic investigation was performed to obtain the normal value of BMD in men and women of NanNing area by the X-ray Bone Mineral Measurement System（XBMS）. The standard of clinical diagnosis of osteoporosis is built. Methods 1092 cases（561 cases in men, 531 cases in women） of healthy persons were examined by XBMS. The data of BMD of distal end of Radius and Ulna were statistically processed. The peak value of men and women were determined. The clinical diagnosis standard of osteoporosis is established. Results The data of clinic investigation shows that the peak value of BMD in men and women is in the age group of 30-39 years old. BMD = 0.867 ± 0.123g/cm^2 in men;BMD = 0.778 ± 0.072g/cm^2 in women. The BMD were decreased after the peak value with age increase. Conclusion The clinic investigation shows that the XBMS has good accuracy and precision. The operation is simple. The method is easily popularized.
