摘要
放射线测量骨矿的原始数据是骨矿含量(bone mineral content,BMC)。由于该值与骨大小和(或)体重成正比,因而用骨投影面积、骨体积和体重标准化BMC以消除它们的影响,分别称为面积骨密度、体积骨密度和体重标准化BMC(BMC/体重)。用面积骨密度诊断骨质疏松,易造成漏诊和误诊;体积骨密度可消除骨大小的影响,但整体骨体积尚难于在活体中获得;体重标化BMC,数据易获得,且在应用中初步表现出其优越性,可能在骨质疏松诊断应用中有较好的前景。
Bone mineral content（BMC） is the basical data for measuring bone mass with radioactive rays. This index is direct proportion with bone size and/or weight. BMC is adjusted by bone area, bone volume and weight and excluding their influence to BMC, we call them respectively areal BMD, volumetric BMD and weight adjusted BMD. Osteoporosis diagnosed by areal BMD may induce missed diagnosis and erroneous diagnosis. Volumetric BMD is acquired difficultly. BMC adjusted by weight is easily acquired and has advantage in diagnosing osteoporosis.
