The purpose of this study is to analogize the result of test when we don't measure two devices through explaining the correlation of bone mineral density (BMD) test value between Lumbar Spine BMD by DXA and QCT of equipment. We analyzed the correlation of lumbar spine by DXA with Trabecular in QCT for BMD and the correlation of lumbar spine with T-score & Z-score QCT for BMD each other. The measuring devices were Hologic QDR-4500w of HOLOGIC INC and SOMATOM 128slice of SIEMENS. We measured the bone mineral density from sixty healthy subjects (10 people in 20~30, 30~40, 40~50, 50~60, 60~70 and 70~80respectively with age). As age roses, T-score became lower. Over 60 occurred osteopenia. Lumbar Spine BMD by DXA and QCT had a high correlation. And T-score of DXA and QCT correlated with Z-score. The research result, we predict the results of one of the devices, through the other's result . So, it could have a clinical availability.
