The axial values of microarchitectural quantitative analysis of an ROI in the femurtrabecular bone.

BV/TV, bone volume to tissue volume (%); BS/BV, bone surface to bone volume (1/mm); Tb.Th, trabecular thickness (mm); Tb.N, trabecular number (1/mm); Tb.Sp, trabecular separation (mm); The x, y, and z axes express the quantities of the 3D structure; Avg, average quantities of the vector sum of the x, y, and z axes.*P0.05 vs. C, **P0.01 vs. C, #P0.05 vs. HLU, ##P△△P△PThe axial values of microarchitectural quantitative analysis of an ROI in the femurtrabecular bone.BV/TV：骨体积与组织体积之比（%）；BS/BV：骨表面积与骨体积之比（单位：1/mm）；Tb.Th：骨小梁厚度（单位：mm）；Tb.N：骨小梁数量（单位：1/mm）；Tb.Sp：骨小梁间距（单位：mm）。X、Y、Z轴用于表征三维结构的各项参数；Avg代表X、Y、Z三轴矢量和的平均参数。*P<0.05 与C组比较，**P<0.01与C组比较，#P<0.05与HLU组比较，##P<0.01与HLU组比较。上述参数为股骨小梁骨感兴趣区（Region of Interest，ROI）的微结构定量分析轴向值。
