目的:分析生活在黔南地区10年以上的苗族、布依族中老年女性骨质疏松症患者骨密度,探讨定量CT(QCT)测定椎体骨密度(BMD)在诊断骨质疏松症中的临床价值.方法:收集在医院接受腰椎QCT检查的100例骨质疏松症中老年女性,年龄47~86岁,按每10岁为一个年龄段分为5组;采用QCT测定受检者BMD,扫描线定位于L2-4椎中间层面,与椎体平行扫描;分析受检者骨质疏松症BMD情况.结果:经QCT测量,5组骨质疏松症患者BMD明显下降,BMD均低于80 mg/cm3.所有骨质疏松症患者BMD随年龄增高而下降,且为严重骨质疏松症.结论:QCT诊断骨质疏松症敏感、准确、重复性强,易于推广应用,腰椎QCT骨密度测量对中老年女性骨质疏松症的早期诊断具有重要作用.%Objective:To discuss the clinical value of bone mineral density (BMD) for vertebral body detected by quantitative CT (QCT) in the diagnosis of osteoporosis through analyzing the BMD situation of middle-aged and older women with osteoporosis of the Miao nationality and the Bouyei nationality who have lived in Qiannan district over 10 years. Methods: 100 middle- aged and old women with osteoporosis diagnosed by quantitative CT for vertebral body were collected and their ages were from 47 to 86 years old. They were divided into 5 groups according to every 10 years old in one group. Their BMD situation were detected by QCT, and the scan lines were located in intermediates of L2-4 vertebral body and the scan should parallel with vertebral body. The BMD situations of these patient with osteoporosis were analyzed depended on above data.Results: Through QCT detection, the BMD of 5 groups of patients with osteoporosis were obviously decreased, and all of BMD were lower than 80mg/cm3. The decline of BMD were correlative with the increasing of ages for all of these patients were severe osteoporosis.Conclusion: QCT is sensitivity, accuracy and better repeatability, and can be conveniently popularized and applied. This method has important value on the early diagnosis of osteoporosis for middle-age and old women.
