骨矿物质含量(BMC)测定方法很多,如普通X线平片、CT扫描、光子吸收和中子活化分析等,但方法复杂、价格昂贵,且不能或难以准确定量。髂骨活检虽能精确定量,但有创伤,多数患者难以接受。骨密度仪可准确地反映局部骨组织矿物质的含量,从而间接了解全身骨组织的情况。我们用国产骨密度仪对正常人和甲状腺功能亢进症(甲亢)患者的桡、尺骨进行了测量,以了解正常人局部的BMC和甲亢对局部BMC的影响。 Bone mineral content (BMC) determination of many ways, such as plain radiography, CT scan, photon absorption and neutron activation analysis, but the method is complex, expensive, and can not be or difficult to accurately quantify. Although iliac biopsy can be accurately quantified, but trauma, the majority of patients unacceptable. Bone density meter can accurately reflect the local bone mineral content, which indirectly understand the situation of whole body bone. We measured the radial and ulna of normal and hyperthyroidism (hyperthyroidism) patients by using domestic bone mineral density meter to understand the effect of local BMC and hyperthyroidism on local BMC.
