Relationships of the backscatter coefficient (BC), the apparent integrated backscatter (AIB), and the integrated reflection coefficient (IRC) with the bone mineral density (BMD) and the microarchitectural parameters were investigated in 28 bovine femoral trabecular bone samples. The BC was highly correlated with the BMD and the microarchitectural parameters (R = −0.66 to 0.71). In contrast, the AIB and the IRC exhibited high correlations with the BMD and the bone volume fraction (R = −0.68 to 0.77) and relatively lower correlations with the remaining microarchitectural parameters (R = −0.62 to 0.60). The multiple regression models yielded the adjusted squared correlation coefficients of 0.54–0.76.

超声反向散射测量与牛小梁骨中骨矿物质密度和微结构参数的关系。

在28个牛股小梁骨样本中研究了背向散射系数（BC），表观积分背向散射（AIB）和积分反射系数（IRC）与骨矿物质密度（BMD）和微结构参数的关系。BC与BMD和微结构参数高度相关（R = -0.66至0.71）。相反，AIB和IRC与BMD和骨体积分数具有较高的相关性（R = -0.68至0.77），而与其余微体系结构参数的相关性较低（R = -0.62至0.60）。多元回归模型得出的校正平方相关系数为0.54-0.76。
