One of the most common causes of lumbar scoliosis in adults is the decreased bone mineral density (BMD). The scoliosis in the lumbar spine has a known effect over the dual-energy X-ray absorptiometry (DXA) scan results. The objective of this study is to assess the influence of the lumbar scoliosis on the results of the DXA scan of the lumbar spine. 1019 women aged ≥40 years underwent a DXA scan of the spine. Age, weight, height, total BMD, total Tscore of the lumbar spine were recorded. The angle of the lumbar scoliosis (Cobb's angle) was measured from the DXA scan image using a DICOM software. The incidence of lumbar scoliosis in the current study accounts to 12.3%. Women with scoliosis showed significantly higher incidence of discrepancy in BMD T-scores between the adjacent vertebrae by more than 1 SD compared to women without scoliosis, (p=0.046). DXA results of subjects with scoliosis require more detailed evaluation of the T-scores of each vertebra to make a prompt decision about the final diagnosis.
成人腰椎侧弯最常见的原因之一是骨密度（BMD）降低。腰椎侧弯对双能X线吸收法（DXA）扫描结果有已知影响。本研究的目的是评估腰椎侧弯对腰椎DXA扫描结果的影响。1019名年龄≥40岁的女性接受了脊柱DXA扫描。记录年龄、体重、身高、腰椎总骨密度、总T值。使用DICOM软件从DXA扫描图像测量腰椎侧弯角度（Cobb角）。本研究中腰椎侧弯的发生率为12.3%。与无侧弯的女性相比，有侧弯的女性相邻椎体间BMD T值差异超过1个标准差的发生率显著更高（p = 0.046）。有侧弯受试者的DXA结果需要对每个椎体的T值进行更详细评估，以便对最终诊断迅速做出决定。
