Abstract:
Objective To assess the accuracy of SIEMENS Osteo software.Methods The mineral content of 20 cadaver lumber bodies(L 1～L 5) was measured by quantitative CT,and compared with bone ash analysis.Results Mineral content and bone ash weight had a linear correlation,which could be expressed by followed regress equation:ash weight=0.92432?BMD+39.0633.The results with quantitative CT method were all lower than that with bone ash analysis (average lower 29.196 mg/cm 3).Conclusion There are some deviations for measuring bone mineral content with this software.The deviation is within the limit of the theory error of single energy quantitative CT.The result of the measurement shoud be accurate after proofread.
