骨矿定量检查中不能忽视X线平片的重要性

The Importance of Radiograph should not be Ignored in Bone Mineral Quantitative Measurement

目的:骨矿定量检查中不能忽视X线平片的重要性。材料与方法:使用双能X线吸收法(DXA)对5例病人的全身及腰椎进行测定。结果:X线平片显示5例皆有不同程度的骨减少及退行性脊椎病。2例腹主动脉钙化,1例棘间、棘上韧带钙化。DXA测量,5例患者的全身骨量均低于正常值,而4例腰椎骨量都高于正常峰值。结论:强调各种骨矿定量检查方法必须结合X平片检查,才能发挥更大作用。

Purpose: Imaportance of radiographic examination should not be ignored in bone mineral quantitative measurement. Materials and Methods: BMD of the lumbar and total body skeleton was measured using dual energy X-ray absorptiometry (DXA) in five patients and the relationship between manifestations of radiograph and BMD was analyzed. Results: The radiographs demonstrated that osteopenia and degenerative spondylosis in defferent degree were found in all patients. The calcification of aorta and ligament were observed in two and one cases, respectively. The BMD of lumbar 2 - 4 th were higher than normal in 4 cases although all cases showed that the BMD of total body skeleton were lower than the normal peak. Conclusion: In order to elevate the diagnostic accuracy, the importance of radiographic manifestations combined with BMD measurement should not be ignored.
