单、双光子吸收法单、双光子吸收法 SPA采用单一波长的γ射线125碘或241镅为发射源，计算其经过被测物后衰减率，再经一已知标准将其衰减值转换为骨矿含量或骨密度。通常只对四肢骨骼(如桡骨、尺骨)进行测量，并且主要测量皮质骨。为校正软组织产生的变异，测量时受检部位置于与软组织等当量的水袋中，采用多次扫描并取其均数，再除以受检骨的宽度，得骨的面密度，骨密度单位是g/cm2，其准确性约为6%，精确性在1%～2%，辐射剂量较小，通常低于10mRem(毫雷姆)。双光子吸收法(DPA)采用能发射两种不同能量光子的核素作放射源，利用高能和低能射线通过被测部位的不同衰减分布来计算骨的能量衰减分布，故可用来测量一些软组织变异大的部位如脊椎、髋等全身部位的骨矿含量，从而消除软组织及脊髓对测量结果的影响。DPA通常测量L1～L4的骨矿含量，结果以骨矿密度g/cm2表示。且辐射剂量较低，3～5μSv(4～6)。缺点为检查时间较长，并且DPA的测量是射线所经通路的衰减值的总和，无法区分皮质骨和松质骨的骨密度，另外，全身的骨矿含量的测量还受椎体边缘骨赘、椎体小关节肥大、压缩性骨折和钙化血管的影响。
