A comparison between forearm bone mineral content (BMC) and lumbar BMC was made in post-menopausal women. Women without symptoms, women with clinical spinal osteoporosis, and women with prednisone-treated rheumatoid arthritis were studied. A conventional two-dimensional single-photon osteodensitometer was used for measurement of forearm BMC. A new two-dimensional dual-photon osteodensitometer was used for measurement of lumbar BMC. Its radioactive source was 153Gadolinium. The mean lumbar BMC was significantly reduced in women with clinical spinal osteoporosis (P < 0.001). The mean forearm of BMC of those patients was normal. Thus, forearm BMC was a poor indicator of spinal osteopenia. If forearm BMC was used to predict lumbar BMC erroneously high results were obtained in women with clinical spinal osteoporosis, and erroneously low values were obtained in prednisone-treated women with rheumatoid arthritis.
对绝经后女性的前臂骨矿物质含量(BMC)和腰椎BMC进行了比较。研究了无症状女性、患有临床脊柱骨质疏松症的女性以及接受泼尼松治疗的类风湿性关节炎女性。使用传统的二维单光子骨密度仪测量前臂BMC。使用一种新型二维双光子骨密度仪测量腰椎BMC。其放射源为钆-153。患有临床脊柱骨质疏松症的女性腰椎BMC平均值显著降低(P < 0.001)。这些患者的前臂BMC平均值正常。因此,前臂BMC是脊柱骨质减少的一个较差指标。如果用前臂BMC来预测腰椎BMC,患有临床脊柱骨质疏松症的女性会得出错误的高值,而接受泼尼松治疗的类风湿性关节炎女性会得出错误的低值。
