Subjects and Methods We measured bone mineral density(BMD), bone mineral content(BMC)and bone area(BA)with dual-energy x-ray absorptiometry bone densitometer in different regions of hip in 3614 Chinese women,aged 20 years and older,and calculated the volumetric BMD(vBMD)at the femoral neck.

对象和方法采用双能X线吸收法骨密度仪测量3614例20岁以上中国女性髋部各区域的骨密度(BMD)、骨矿含量(BMC)和骨面积(BA),并计算股骨颈的体积骨密度(vBMD)。

Dual-energy X-ray absorptiometry(DEXA),scanning electron microscopy,and bone biomechanical test were used to assess comprehensively bone quantity and quality of ovariectomized rats.
