To evaluate ultrasound transmission velocity (UTV) for assessment of mechanical bone quality, an ex vivo comparison of different bone types measured with UTV, 2-dimensional (2D) histomorphometry and with 3-dimensional (3D) radiology (cone-beam computerized tomography [CBCT], computerized microtomography [μCT]) was conducted.
Clinical cortical, cancellous, and mixed bone (each n = 6) was measured via UTV (m/s), CBCT (white pixel/black pixel ratio [WP/BP]), μCT (bone volume/total volume [μBV/TV]), and histomorphometry (bone volume/total volume [hBV/TV]). UTV values were correlated with 2D-histomorphometry and 3D-radiologic results.
For the cortical, cancellous, and mixed bone samples, respectively, UTV values were 1,945.17, 1,266.9,and 1472.2 m/s, WP/BP quotients were 0.96, 0.15, and 0.33, μBV/TV quotients were 0.94, 0.2, and 0.47, and hBV/TV quotients were 0.96, 0.24 and 0.39. Significant correlations between UTV and the other methods were seen (P < .0001).
Similar to the other methods, UTV is able to discriminate between different bone types ex vivo.
评估超声传播速度（UTV）在评估机械骨质量方面的作用，对不同骨类型进行体外比较，分别采用 UTV、二维（2D）组织形态计量学和三维（3D）放射学（锥形束计算机断层扫描 [CBCT]、计算机微断层扫描 [μCT]）进行测量。
通过 UTV（m/s）、CBCT（白像素/黑像素比值 [WP/BP]）、μCT（骨体积/总体积 [μBV/TV]）和组织形态计量学（骨体积/总体积 [hBV/TV]）对临床皮质骨、松质骨和混合骨（每组 n = 6）进行测量。将 UTV 值与 2D 组织形态计量学和 3D 放射学结果进行相关性分析。
分别为皮质骨、松质骨和混合骨样本的 UTV 值为 1945.17、1266.9 和 1472.2 m/s，WP/BP 比值为 0.96、0.15 和 0.33，μBV/TV 比值为 0.94、0.20 和 0.47，hBV/TV 比值为 0.96、0.24 和 0.39。UTV 与其他方法之间存在显著相关性（P <.0001）。
与其他方法一样，UTV 能够在体外区分不同的骨类型。
