摘要
2型糖尿病(type 2 diabetes mellitus,T2DM)通过多种机制引起骨质疏松,定量计算机断层扫描(quantitative computed tomography,QCT)和双能X线吸收仪(dual energy X-ray absorptiometer,DXA)是常用的检测骨质疏松的手段。对于T2DM患者骨质疏松的诊断,QCT在机制上优于DXA,QCT可以提供骨微结构的测量且不受受试者体型大小和骨骼大小的影响。DXA虽然易受受试者体型大小和骨骼大小的影响,存在一定缺陷,但调整BMI之后的结果具有一定的可信度。
Type 2 diabetes mellitus(T2 DM) causes osteoporosis by several mechanisms. Quantitative computed tomography(QCT) and Dual Energy X-ray absorptiometer(DXA) are commonly used to detect osteoporosis. For the diagnosis of osteoporosis in patients with T2 DM, QCT is superior to DXA in mechanism. QCT can provide the measurement of bone microstructure without impacts by the body size and bone size of subjects. Due to the influence of body size and bone size of subjects, DXA has limitation in some extent, however, after adjusting with BMI, the result is of certain credibility.
