Micro-computed tomography (micro-CT) is a special CT to examine biopsy bone samples or small animal bones in vitro, and it can provide high resolution images (20-30 microns) precisely representing the two-dimensional and three-dimensional microstructure of the trabecular bone. The quantification of trabecular connectivity and anisotropy, which is believed to be strongly related to the bone strength, can be done with micro-CT. In comparison with histomorphometry and scanning electron microscopy, micro-CT has the advantage of requiring less efforts and time. Besides, micro-CT provides higher resolution than micro-magnetic resonance. So far, micro-CT is believed to be the best method to analyze the three-dimensional structure in vitro.
微计算机断层扫描（micro-CT）是一种特殊的CT，用于在体外检查活检骨样本或小动物骨骼，它能够提供高分辨率图像（20 - 30微米），精确呈现松质骨的二维和三维微观结构。可以使用micro-CT对与骨强度密切相关的小梁连接性和各向异性进行量化。与组织形态计量学和扫描电子显微镜相比，micro-CT具有所需工作量和时间较少的优势。此外，micro-CT提供的分辨率高于微磁共振。到目前为止，micro-CT被认为是体外分析三维结构的最佳方法。
