双能X射线吸收测定法测量身体成分的应用及研究进展

Advances in the application and research of dual energy X-ray absorptiometry in measuring body compositions

双能X射线吸收测定法(DXA)具有辐射剂量低、重现性好、扫描时间短和容易获得等优势,广泛应用于临床和科研中。DXA体成分分析可检测骨密度、脂肪质量、瘦体质量、去脂肪质量和体脂率等多种身体成分。目前,DXA体成分分析在各种临床疾病的诊断、治疗及风险评估中被广泛地应用,笔者就DXA体成分分析在一些临床疾病中的应用及最新研究进展作简要综述。

Dual energy X-ray absorptiometry(DXA)is widely used in clinical and scientific research due to its advantages of low radiation dose,good reproducibility,short scanning time and easy access.DXA body composition analysis can detect various body compositions,including bone density,fat mass,lean body mass,fat-free mass,body fat rate and so on.It has been widely used in the diagnosis,treatment and risk assessment of various clinical diseases.This review is focused on the application of DXA body composition analysis and the latest research in some clinical diseases.
