Diagnostic discordance for osteoporosis is the observation that the T-score of a patient varies between skeletal sites, falling into 2 different diagnostic categories identified by the World Health Organization classification system. Densitometrists and clinicians should expect that at least 4 of every 10 patients tested by dual-energy X-ray absorptiometry (DXA) to demonstrate T-score discordance between spine and total hip measurement sites. T-score discordance can occur for a variety of reasons related to physiologic and pathologic patient factors and the performance or analysis of DXA itself.
骨质疏松症的诊断不一致是指患者的T值在不同骨骼部位之间存在差异，落入世界卫生组织分类系统所确定的两种不同诊断类别。骨密度测量师和临床医生应预计，每10名接受双能X线吸收测定法（DXA）检测的患者中，至少有4人会出现脊柱和全髋测量部位之间的T值不一致。T值不一致可能由多种与患者生理和病理因素以及DXA本身的性能或分析相关的原因引起。
