DXA在诊断主动脉钙化中的应用进展

Progress in the diagnosis of aortic calcification with dual energy X-ray absorptiometry

双能X线骨密度吸收仪(DXA)通常被用于测定骨密度(BMD)以诊断骨质疏松,近年研究发现,DXA同时应仔细观察主动脉有无钙化,而主动脉钙化是冠心病的重要危险因素,发现异常者应结合被检者的年龄、冠心病风险因素等情况提出进一步检查的建议。这样,在检测骨密度的同时检测主动脉的钙化,无论是对骨质疏松还是冠心病的发生均可以起到早期诊断、早期治疗的目的 。

Dual energy X-ray absorptiometry is generally used to measure bone mineral density for diagnosis of osteoporosis. Recent research results support that aortic calcification might be found during DXA measuring. Because aortic calcification is associated with coronary heart disease, so caution should be taken about aortic calcification when DXA was done and further cheekhst may be raised as a result. Thinking about aortic calcification when bone mineral density was measuring by DXA was important for early diagnosis and treatment of osteoporosis and coronary heart disease.
